3. Question Who was granted the first U.S. Patent for mechanical refrigeration in 1851? ▫John Gorrie ▫Willis Carrier ▫James Trane ▫John Gorrie 3

4. John Gorrie 1837 - physician for the Marine Hospital Service in Florida Worked with malaria and yellow fever victims – needed to lower their body temperatures Believed these diseases were caused by extreme heat and humidity Believed that cold was a healer and advocated the cooling of sickrooms 4

5. John Gorrie 5

6. Ice had to be brought by boat from the northern lakes Ice was expensive and Gorrie wanted a cheaper way to get the ice Developed the first steam-driven compressor to cool air, which led to development of the first ice-making machine Saw cooling potential for buildings and ships (preserving “organic matter”) 6

8. NY Journalist. “A crank down in Florida thinks he can make ice as good as Almighty God…” 1851. Gorrie receives a U.S. patent on his ice machine and his chief financial backer dies Ice farmers worked against the development of the device Gorrie conclusion - Mechanical refrigeration "has been found in advance of the wants of the country." Financial ruin, a nervous collapse, and dies in seclusion in 1855 at age 51 8
