Robert Daniel Carmichael

Robert Daniel Carmichael (March 1, 1879 – May 2, 1967) was an American mathematician.
== Biography ==

Carmichael was born in Goodwater, Alabama. He attended Lineville College, briefly, and he earned his bachelor's degree in 1898, while he was studying towards his Ph.D. degree at Princeton University. Carmichael completed the requirements for his Ph.D. in mathematics in 1911. Carmichael's Ph.D. research in mathematics was done under the guidance of the noted American mathematician G. David Birkhoff, and it is considered to be the first significant American contribution to the knowledge of differential equations in mathematics.
Carmichael next taught at Indiana University from 1911 to 1915. Then he moved on to the University of Illinois, where he remained from 1915 until his retirement in 1947.
Carmichael is known for his research in what are now called the Carmichael numbers (a subset of Fermat pseudoprimes, numbers satisfying properties of primes described by Fermat's Little Theorem although they are not primes), Carmichael's totient function conjecture, Carmichael's theorem, and the Carmichael function, all significant in number theory and in the study of the prime numbers. He found the smallest Carmichael number, 561, and over 50 years later, it was proven that there are infinitely many of them. Carmichael may have been the first to describe the Steiner system S(5,8,24), a structure often attributed to Ernst Witt.
While at Indiana University Carmichael was involved with special theory of relativity.〔For original papers on special theory of relativity see wikisource:Author:Robert Daniel Carmichael.〕
