Rufus Oldenburger (6 July 1908, Grand Rapids, Michigan – 1969) was an American mathematician and mechanical engineer.
Education and career.
Oldenburger received from the University of Chicago an A.B. degree 1928, a master's degree in mathematics in 1930, and a Ph.D. in 1934. After teaching mathematics at the University of Michigan, at the Case Institute of Technology, at Illinois Institute of Technology, and at DePaul University, he changed the focus of his research from pure mathematics to mechanical engineering and automatic
Kolakoski sequence
In mathematics, the Kolakoski sequence, sometimes also known as the Oldenburger-Kolakoski sequence, is an infinite sequence of symbols {1,2} that is its own run-length encoding and the prototype for an infinite family of related sequences. It was initially named after the recreational mathematician William Kolakoski (1944–97), who discussed it in 1965, but subsequent research has revealed that it first appeared in a paper by Rufus Oldenburger in 1939.
