Biography:Charles Herschel Sisam
Charles Herschel Sisam (8 September 1879, Cedar Rapids, Iowa – 4 December 1964) was an American mathematician.[1][2] He received his B.A. in 1902 from the University of Michigan and then his M.A. in 1903 and Ph.D. in 1906, under the supervision of Virgil Snyder, from Cornell University.[3] While working on his Ph.D., Sisam was a mathematics instructor at the United States Naval Academy from 1904 to 1906.[4] He was an instructor in 1906–1907, a research associate in 1907–1909, and an assistant professor in 1909–1918 at the University of Illinois. From 1918 to 1948, he was a full professor at Colorado College. He did research on algebraic surfaces and was an Invited Speaker at the ICM in 1928 in Bologna.[5] He was on the editorial staff of the Transactions of the American Mathematical Society from 1930 to 1936.
Sisam married and was the father of a daughter.
