Meyer was on the faculty of the University of California for sixty-one years, including thirty years as Director of the George Williams Hooper Foundation for Medical Research (1924-1954), the Universitys first biology research facility.
Meyer, or "KF" as he was familiarly known, was educated in his native Switzerland, and came to Berkeley in 1913 as Associate Professor of Bacteriology and Protozoology.
In 1928, Meyer began to refer to the disease in California as 'sylvatic plague' and predicted that "plague is going to be an infection with which we have to learn to live." He proposed that large reservoirs of Pasteurella pestis reside in wild rodents.
KarlF. Meyer (or "K.F." as he was known to the scientific world) was born in 1884 in Basel, Switzerland.
Meyer was well received as the teacher of medical microbiology, and was a full Professor by the age of thirty.
Meyer organized the Department of Bacteriology at UC, and in the college of Letters and Science at Berkeley, serving as Chairman of both departments until 1948, while also directing the affairs of the Hooper foundation.
