Dr. Cook was born in Owasso, Michigan, August 30, 1842, and 
passed his boyhood in that state. In 1862 he graduated from 
Michigan Agricultural College and then was a graduate student in 
Harvard University for a year. He then returned to his Alma 
Mater as professor of entomology and zoology in which position he 
remained until 1893. In that year he came west to California 
and from 1894 to 1911 was professor of biology in Pomona Col- 
lege. In 1911 he went to Sacramento, but retained his connection 
with this college as emeritus professor. On September 29, 1916, 
in his boyhood home in Owasso, Michigan, he passed on from his 
arduous labors on this earth to his great reward.
