S. L. Hakimi
Seifollah Louis Hakimi (1932 – June 23, 2005) was an Iranian-American mathematician born in Iran, a professor emeritus at Northwestern University, where he chaired the department of electrical engineering from 1973 to 1978. He was Chair of the Department of Electrical Engineering at University of California, Davis, from 1986 to 1996.
Hakimi received his Ph.D. from the University of Illinois at Urbana-Champaign in 1959, under the supervision of Mac Van Valkenburg. He has over 100 academic descendants, most of them via his student Narsingh Deo.

A proof of this theorem was first published by Václav Havel ... in 1963 another proof was published independently by S. L. Hakimi.

The Steiner tree problem in networks was originally formulated by Hakimi and independently by Levin in 1971.

On p. 53, Marianov and Serra write "The impact of Hakimi's two contributions is hard to overstate. A common opinion among location researchers is that the paper by Hakimi (1964) strongly contributed to trigger the interest in location theory and analysis, and started a long string of related publications that does not seem to be decreasing."
