Robert Koch

Born 11 Dec 1843; died 27 May 1910 at age 66. (Heinrich Hermann) Robert Koch was a German physician, a founder of the science of bacteriology, who discovered the tubercle bacillus (1882) and the cholera bacillus (1883). He studied bubonic plague in Bombay (1897) and malaria and sleeping sickness in Africa. In addition Koch investigated tropical dysentery, and the Egyptian eye disease (trachoma), and typhus recurrens in tropical Africa. He also carried out work of exceptional importance concerning destructive tropical cattle diseases, such as rinderpest, Surra disease, Texas fever, coast fever in cattle and the trypanosome disease carried by the tsetse fly. He won the Nobel Prize for Physiology or Medicine in 1905, "for his investigations and discoveries in relation to tuberculosis."

MONDAY: It's fun to cook for...

MONDAY: It's fun to cook for Tom. Today I made angel food cake. The recipe said beat 12 eggs separately. The neighbors were nice enough to loan me some extra bowls.
TUESDAY: Tom wanted fruit salad for supper. The recipe said serve without dressing. So I didn't dress. What a surprise when Tom brought a friend home for supper.
WEDNESDAY: A good day for rice. The recipe said wash thoroughly before steaming the rice. It seemed kind of silly but I took a bath anyway. I can't say it improved the rice any.
THURSDAY: Today Tom asked for salad again. I tried a new recipe. It said prepare ingredients, lay on a bed of lettuce one hour before serving. Tom asked me why I was rolling around in the garden.
FRIDAY: I found an easy recipe for cookies. It said put the ingredients in a bowl and beat it. There must have been something wrong with this recipe. When I got back, everything was the same as when I left.
SATURDAY: Tom did the shopping today and brought home a chicken. He asked me to dress it for Sunday (oh boy).For some reason Tom keeps counting to ten.
SUNDAY: Tom's folks came to dinner. I wanted to serve roast but all I had was hamburger. Suddenly I had a flash of genius. I put the hamburger in the oven and set the controls for roast. It still came out hamburger, much to my disappointment.
GOOD NIGHT DEAR DIARY. This has been a very exciting week. I am eager for tomorrow to come so I can try out a new recipe on Tom. If I can talk Tom into buying a bigger oven, I would like to surprise him with chocolate moose.
