1 INVENTIONS Then and Now

2 VOCABULARY Allowed: let someone do something Design: a drawing or outline used as a pattern Instrument: a tool to help you do something Invented: to make or think of something first time Powerful: having great power and importance Products: things that are made or created

3 KID INVENTORS THEN AND NOW Chester Greenwood was a fifteen-year-old who lived in the 1800s. Chesters parents allowed him to play outside. They let him go out even in the wintertime. Chester lived in Maine, where the winters are cold. There is lots of snow and powerful, strong winds. Chester would get very cold, but he wouldnt wear a hat.

4 Chester decided to create something to solve his problem. He invented a way to keep his ears warm. He used an instrument, or tool, to bend wire into loops. His grandmother then sewed fur onto them. Chester had created the first pair of earmuffs!

5 More than 100 years later, cold, snowy weather also gave ten-year-old K-K Gregory an idea. Snow kept getting up her coat sleeves. She looked in many stores to find an item to solve her problem. She couldnt find any good products. So K-K made a design for a new kind of glove.

6 She drew and described something she called wristies. Wristies are long gloves without fingers. They were a big hit with people living in cold places all over the world!


8 INTRODUCTION Inventors create new things. Their inventions solve problems or make life better in some way. Throughout our history, African-Americans have invented many important things.

9 John Lee Love received a patent for a pencil sharpener in 1887.

10 Garrett Morgan received a patent for an early type of traffic signal on November 20, 1923.

11 John Purdy and James Sadgwar patented a folding chair in 1889.

12 Benjamin Banneker Benjamin Banneker was born on a farm in Maryland in At that time, Maryland was one of thirteen British colonies in North America.

13 Most African-American people in colonies were enslaved, but Benjamins parents were free. Because Benjamin was born to a free family, he could go to school.

14 Benjamin Banneker grew up near Baltimore, Maryland in the mid-1700s. HISTORICAL MAP

15 Benjamin went to a local school for boys. He was so good at math that he soon knew more than his teacher. After he finished his education, Benjamin worked on the family farm.

16 Benjamins life changed when he was twenty years old. He met a man who owned a pocket watch. The watch had been made in Europe. Benjamin was so interested in the watch that the man let him keep it.

17 Benjamin studied the watch, its parts, and the way it was made. He decided to make his own clock out of wood. It was the first clock ever made in North America. HIS WOODEN CLOCK RAN PERFECTLY FOR MORE THAN 40 YEARS.

18 Benjamin used his clock to measure the movements of the stars. He used math to figure out the position of the stars, sun, moon, and planets.

19 Farming in the 1700s was done by hand. Tractors and other farm machines had not been invented yet.

20 Benjamin wrote a new almanac every year for six years. People read it to find out when the sun and moon would rise and set. They read it to find out how the weather would change each season. Many farmers used his almanacs so they would know when to plant their crops. He was as famous for his almanac as he was for his clock.

21 FOR THE TEACHER: Benjamin Banneke Benjamin Banneker was a largely self-educated mathematician, astronomer, compiler of almanacs, inventor and writer. Benjamin Banneker was born November 9, 1731, in Ellicott's Mills, Maryland. He was the son of an ex-slave named Robert, whose wife, Mary Banneky, was the daughter of an Englishwoman and an African ex-slave. Because both of his parents were free, Benjamin escaped the wrath of slavery as well. He was taught to read by his grandmother, Molly, and for a short time attended a small Quaker school. For the most part, though, Banneker was self-educated, a fact that did little to diminish his brilliance. His early exploits included constructing a wooden clock in his early twenties, despite having seen only one other timepiece in his life. In addition, Banneker taught himself astronomy and accurately forecasted lunar and solar eclipses. Banneker's talents and intelligence eventually came to the attention of the Ellicott brothers, industrialists who had made their name and fortune by building a series of gristmills in the Baltimore area in the 1770s. George Ellicott, a fellow mathematician and astronomer, loaned Banneker numerous books in both fields. In 1791 Banneker teamed up with Major Andrew Ellicott, an American surveyor, to map out the new national capital, Washington, D.C.

22 Banneker's Almanacs Banneker's true acclaim, however, came from his almanac, which he published for six consecutive years between 1792 and These almanacs included his own astronomical calculations as well as opinion pieces, literature, and medical and tidal information, among other things. Outside of his almanacs, Banneker also published information on bees and calculated the cycle of the 17-year locust. Letter to Jefferson Banneker's confidence extended into other realms. During Thomas Jefferson's tenure as secretary of state, Banneker wrote the respected Virginian and attacked his proslavery stance. He criticized Jefferson, a slave owner himself, for his "absurd and false ideas" and urged him to recognize that "one Universal Father…afforded us all the same sensations and endowed us all with the same faculties." To his credit, Jefferson acknowledged Banneker's letter, writing him a response, which Banneker published alongside his original piece of correspondence in his 1793 almanac. Banneker's outspokenness with regard to the issue of slavery earned him the widespread support of the abolitionist societies in Maryland and Pennsylvania, both of which helped him publish his almanac. Benjamin Banneker died in Baltimore, Maryland, on October 25, He was buried at the family burial ground near his house

23 SARAH E. GOODE We know very little about Sarah E. Goode. What we do know is that she was the first African-American woman to receive a patent for an invention.

24 A patent is a legal paper. It is given out by the United States government in Washington, D.C. A person who invents something can get a patent to prove that he or she was the first to have made it. No one else can say they invented the same thing.

25 Sarah was born in a southern state in She was born into slavery. When slavery ended, Sarah was a teenager. She was able to go to school once she was free. After she received her education, Sarah moved to Chicago, Illinois.

26 Sarah must have been smart and hard working. By the time she was 35 years old, she owned her own business. Sarah Goode was the owner of a furniture store.

27 Many African-American people were moving from southern states to northern states in the 1870s and 1880s. They moved into apartment houses. Sometimes many people slept in one room. This was because many people did not have enough money to rent their own rooms.

28 Sarah had the idea of making a bed that could fit in a small space. It could fold up during the day and unfold at night. She worked out a design. Then she made a model.

29 Sarahs patent showed the cabinet bed design. Folded up it looked like a desk. It opened up into a bed.

30 Sarah called her invention a cabinet bed. When it was folded up, it could be used as a desk. There was even a place for keeping pens and paper.

31 Sarah did not want anyone else to copy her invention. She made sure of that by getting a patent. We do not know how many cabinet beds Sarah made. We do know that her idea is still helpful for people. Folding beds are still in use today. Designed by Sarah Goode.

32 Different folding bed designs have been made over the years.

34 FOR THE TEACHER Sarah E. Goode Born into slavery in 1850, inventor and entrepreneur Sarah E. Goode went on to become the first African-American woman to be granted a patent by the U.S. Patent and Trademark Office, for her invention of a folding cabinet bed in After receiving her freedom at the end of the Civil War, Goode moved to Chicago and eventually became an entrepreneur. Along with her husband Archibald, a carpenter, she owned a furniture store. Many of her customers, who were mostly working-class, lived in small apartments and didn't have much space for furniture, including beds. As a solution to the problem, Goode invented a cabinet bed, which she described as a "folding bed," similar to what nowadays would be called a Murphy bed. When the bed was not being used, it could also serve as a roll-top desk, complete with compartments for stationery and other writing supplies. Goode received a patent for her invention on July 14, She died in 1905.

35 GEORGE WASHINGTON CARVER George Washington Carver was born in Missouri about Like Sarah E. Goode, he was born into slavery. His family was enslaved by a couple named Carver. George was raised by Mr. and Mrs. Carver.

36 George loved the Carver farm, with all of its plants and animals. He planted his own garden. Soon, he knew so much about plants that people called him the Plant Doctor.

37 George wanted to go to school to learn more about plants. Slavery was over, so he was free to leave the Carver farm. It took him twenty years to get enough education and save enough money to enter college. IOWA

38 George went to college in Iowa. He was the first African-American student at the school. He studied farming and learned even more about plants. When he graduated, he became a teacher.

39 George taught at Tuskegee Institute in Alabama. It was a college for African-American people. He studied plants at the college. George told farmers that peanuts and sweet potatoes were good crops to grow.

40 He found that he could make 118 different products from the sweet potato. These included soap, coffee, and glue.

41 George learned that he could do even more with peanuts. He made over 300 different products from peanuts. Some of these were peanut butter, ice cream, paper, ink, shaving cream, and shampoo.

42 George only received three patents for the products he invented. He believed that most of them should belong to everyone.

43 FOR THE TEACHER GEORGE WASHINGTON CARVER Botanist and inventor George Washington Carver was one of many children born to Mary and Giles, an enslaved couple owned by Moses Carver. He was born during the Civil War years, most likely in A week after his birth, George was kidnapped along with his sister and mother from the Carver farm by raiders from the neighboring state of Arkansas. The three were sold in Kentucky, and among them only the infant George was located by an agent of Moses Carver and returned to Missouri. The conclusion of the Civil War in 1865 brought the end of slavery in Missouri. Moses Carver and his wife, Susan, decided to keep George and his brother James at their home after that time, raising and educating the two boys. Susan Carver taught George to read and write, since no local school would accept black students at the time. The search for knowledge would remain a driving force for the rest of George's life. As a young man, he left the Carver home to travel to a school for black children 10 miles away. It was at this point that the boy, who had always identified himself as "Carver's George" first came to be known as "George Carver." Carver attended a series of schools before receiving his diploma at Minneapolis High School in Minneapolis, Kansas. Accepted to Highland College in Highland, Kansas, Carver was denied admittance once college administrators learned of his race. Instead of attending classes, he homesteaded a claim, where he conducted biological experiments and compiled a geological collection. While interested in science, Carver was also interested in the arts. In 1890, he began studying art and music at Simpson College in Iowa, developing his painting and drawing skills through sketches of botanical samples. His obvious aptitude for drawing the natural world prompted a teacher to suggest that Carver enroll in the botany program at the Iowa State Agricultural College.

44 Carver moved to Ames and began his botanical studies the following year as the first black student at Iowa State. Carver excelled in his studies. Upon completion of his Bachelor of Science degree, Carver's professors persuaded him to stay on for a master's degree. His graduate studies included intensive work in plant pathology at the Iowa Experiment Station. After graduating from Iowa State, Carver embarked on a career of teaching and research. Booker T. Washington, the principal of the African-American Tuskegee Institute, hired Carver to run the school's agricultural department in Tuskegee's agricultural department achieved national renown under Carver's leadership, with a curriculum and a faculty that he helped to shape. Areas of research and training included methods of crop rotation and the development of alternative cash crops for farmers in areas heavily planted with cotton. The education of African-American students at Tuskegee contributed directly to the effort of economic stabilization among blacks. Carver pioneered a mobile classroom to bring his lessons to farmers. The classroom was known as a "Jesup wagon," after New York financier and Tuskegee donor Morris Ketchum Jesup. Carver's work at Tuskegee included groundbreaking research on plant biology that brought him to national prominence. Many of these early experiments focused on the development of new uses for crops such as peanuts, sweet potatoes, soybeans and pecans. The hundreds of products he invented included plastics, paints, dyes and even a kind of gasoline. Carver's prominence as a scientific expert made him one of the most famous African-Americans of his time, and one of the best-known African-American intellectuals up to that point. President Theodore Roosevelt admired his work and sought his advice on agricultural matters in the United States. Carver also advised Indian leader Mahatma Gandhi on matters of agriculture and nutrition. Carver used his celebrity to promote scientific causes for the remainder of his life. George Washington Carver died on January 5, 1943, at the age of 78 after falling down the stairs at his home. He was buried next to Booker T. Washington on the Tuskegee grounds. Carver's epitaph reads: "He could have added fortune to fame, but caring for neither, he found happiness and honor in being helpful to the world."

45 PATRICIA BATH, M.D. Patricia Bath was born more than 75 years after George Washington Carver. Patricia was born in a northern state. She grew up in the New York City neighborhood of Harlem.

46 Like George Washington Carver, she was still young when she began to study living things. Her special interest was human diseases. After high school, she got a job helping people who studied cancer.

47 In college, Patricia studied chemistry. Then she went to medical school. She decided to study eye diseases. She wanted to find out how to remove cataracts. HUMAN EYE HUMAN EYE WITH CATARACTS

48 Cataracts are like clouds on the lens of the eye. They make everything look cloudy. Patricia designed an instrument for removing cataracts. It gives off a powerful beam of light that breaks up the cataract. Then it can be removed.

49 In 1988 Patricia received a patent for the instrument she invented. She was the first African-American woman to get a patent for a medical invention. Since then she has invented other eye instruments. Her work has allowed many people to see again.

50 FOR THE TEACHER PATRICIA BATH, M.D. Patricia Era Bath was born on November 4, 1942, in Harlem, New York. Bath was encouraged by her family to pursue academic interests. Her father taught Bath about the wonders of travel. Her mother piqued the young girl's interest in science by buying her a chemistry set. As a result, Bath worked hard on her intellectual pursuits and, at the age of 16, became one of only a few students to attend a cancer research workshop sponsored by the National Science Foundation. The program head, Dr. Robert Bernard, was so impressed with Bath's discoveries during the project that he incorporated her findings in a scientific paper he presented at a conference. The publicity surrounding her discoveries earned Bath the Mademoiselle magazine's Merit Award in After graduating from high school in only two years, Bath headed to Hunter College, where she earned a bachelor's degree in She then attended Howard University to pursue a medical degree. Bath graduated with honors from Howard in 1968, and accepted an internship at Harlem Hospital shortly afterward. The following year, she also began pursuing a fellowship in ophthalmology at Columbia University. Through her studies there, she discovered that African Americans were twice as likely to suffer from blindness than other patients to which she attended, and eight times more likely to develop glaucoma. Her research led to her development of a community ophthalmology system, which increased the amount of eye care given to those who were unable to afford treatment. In 1973, Patricia Bath became the first African American to complete a residency in ophthalmology. She moved to California and became the first female faculty member in the Department of Ophthalmology at UCLA's Jules Stein Eye Institute. In 1976, Bath co-founded the American Institute for the Prevention of Blindness. By 1983, Bath had helped create the Ophthalmology Residency Training program at UCLA-Drew. In 1981, Bath began working on her most well-known invention: the Laserphaco Probe (1986). Harnessing laser technology, the device created a less painful and more precise treatment of cataracts. She received a patent for the device in 1988, becoming the first African-American female doctor to receive a patent for a medical purpose. Bath was able to help restore the sight of individuals who had been blind for more than 30 years.

51 INVENTORS CHANGE THE WORLD The stories of these four inventors show how African-American inventors have helped make life better for all Americans throughout history. Benjamin Banneker helped people keep time and know the positions of the stars and planets. Sarah Goode made furniture for people to use in small homes. George Washington Carver made hundreds of products from sweet potatoes and peanuts. Dr. Patricia Bath invented a cure for one kind of blindness. The world is better because of their work.
