One Cool Invention, a Dino Discovery and Studying Chimpanzees

-- On July 12, 1940: Frederick McKinley Jones received a patent for his creation of air conditioning units on trucks. This important invention helped transport critical food, medicine and blood during World War II, and improved the availability of fresh produce throughout the country. Orphaned at a young age, Jones showed a strong mechanical ability and was a self-taught engineer by the age of 20. He served in the Army during World War I, fixing equipment for the military. A talented engineer, Jones is also credited with the improvement of sound technology that was used in the film industry.

-- On July 13, 1923: American explorer and archaeologist Roy Chapman Andrews discovered dinosaur eggs (later determined to be Oviraptor eggs) in the Gobi Desert in Mongolia. Andrews' expedition also discovered the Protoceratops andrewsi (which was named after him) and a hind leg of what has since been identified as a Shuvuuia (a small feathered dinosaur). He wrote about his many adventures in the book Under a Lucky Star. Andrews was rumored to be the inspiration for the fictional archaeologist Indiana Jones.

-- On July 16, 1960: Jane Goodall first arrived at the Gombe nature reserve (now Gombe Stream National Park) in Tanzania to study chimpanzees. She would ultimately discover several key new facts about the animals. While observing the chimpanzees, she discovered that they would take the leaves off of twigs in order for them to work better for collecting termites to eat, essentially making a type of tool. She also discovered that chimpanzees also hunt other animals, including colobus monkeys, for food. Before her research, most scientists believed that chimpanzees were vegetarians. Goodall has written many scientific articles and books advocating for the protection of chimpanzees and other animals.
