CONTENTS INTRODUCTION EARLY LIFE How he did it WHAT HE DID ADULTHOOD Dieffenbachia Travel in new Zealand Bibliography
INTRODUCTION Johann Karl Ernst Diffenbach, was born in Giessen, Germany, on the 27 th of January 1811. Diffenbach was a German geologist, naturalist and physician, the first trained scientist to live and work in New Zealand. Shortly after his visit to New Zealand, he had to return back to England. He then published a book called ‘ Travel In New Zealand’ in 1843, which tells reports about his visit. Diffenbach tried to return to New Zealand but was unsuccessful. Eventually he settled in Germany and became a geology professor and museum director.
EARLY LIFE Diffenbach attended medical school and got his degree at the university of Giessen. After being accused of trying to overthrow the government he then fled to Zurich. There he received his medical degree. He was then expelled for political reasons, then later in 1837, he arrived in London. He taught German, but was later known for his scientific and medical journals. He became close friends with Charles Lyell and Richard Owen.
How he did it In 1839, Diffenbach sailed to New Zealand on the Tory. He sailed to New Zealand as a surgeon and naturalist, together with his friends Charles Lyell and Richard Owen. He was a well trained medical doctor and was recommended to the New Zealand company, by the Royal Geographical Society. Diffenbach was an unpaid naturalist, and job was to report on the country’s flora, mineral and water resources for new settlement. Diffenbach travelled widely throughout the North Island, and also spent four weeks on the Chatham Islands. He discovered many new species of birds in New Zealand and was the first person to use the term ‘greywacke’ to describe the country’s mountain ranges. The shells, pressed plants, bird skins and rock specimens he collected were sent to London where they were put in the British Museum and the Royal Botanic Gardens at Kew. 1.

Tory Voyage The Tory was a sailing ship, sent to pick up fresh water, food and wood before going to Port Nicholson (Wellington Harbour). On board were, representatives of the New Zealand company, sent for readying the country for new settlers. The group were led by Colonel William Wakefield, brother of the Company's leading figure. He was joined by his brother's son, E. J. Wakefield, naturalist Ernst Dieffenbach, draughtsman Charles Heaphy and interpreter Nahiti. Dr John Dorset had been appointed as Colonial Surgeon and Captain Edward Main Chaffers as master of the ship.
What he did DIffenbach was the first trained scientist to live and work in New Zealand. He wrote numerous reports for the New Zealand Company. He sent collections of animals, rocks and even plants. Many plants are named after him, one of which is called the Dieffenbachia. Other then being the first scientist to work in New Zealand, Diffenbach was also the first person to climb Mount Egmont successfully. Ernst Diffenbach explored many places in the north island. Tongariro, Taupo, Waikato, Whaingaroa, and he even visited the Chatham islands.
What happened After his work for the New Zealand company was completed, Diffenbach offered to make a scientific exploration of New Zealand. But Governor Gipps could not afford his travel expenses, and declined him. In October 1841 Dieffenbach had to return to England, where he published his report on the Chatham Islands in the New Zealand Journal. His book, Travel in New Zealand, was published in 1843. Two years later he wrote a report on the geology of the country to the British Association. Governor Gips
ADULTHOOD Attempts to return to New Zealand were unsuccessful. After the revolution of 1848 he taught at Giessen, where he was later appointed supernumerary professor of geology. He died at Giessen in October 1855. In 1850 he was named adjunct professor of geology in Giessen. Sadly in 1855 Diffenbach died. Information about personal life unavailable

Dieffenbachia The Dieffenbachia was named after Ernst Diffenbach. Dieffenbachia plants can grow outdoors in tropical climates, but if kept as houseplants must be kept indoors during most of the year outside the tropics. Temperatures below about 10˚C can kill the plant. The dieffenbachia plant contain needle-shaped calcium oxalate crystals called Raphides. Dieffenbachia responds well to hot temperatures and dry climates. The sap from the Dieffenbachia is toxic. Its common name “dumb cane”. This plant causes temporary speechlessness when touched to the tongue. Keep out of reach of children and pets. Dieffenbachia Raphides
Travel in New Zealand Click on the link below: http://www.archive.org/stream/travelsinnewzeal01diefrich#pa ge/n5/mode/2up Travel in New Zealand was written by Johann Karl Ernst Diffenbach. The book he wrote was about his travel to New Zealand, it was more of a journal. It told about the different places he visited and different species he discovered. His observations were acute (small) about the natural history he mainly recorded. He wrote recorded many things about the Maori, including a study of their language.
