Steve Selvin (born 1941) is an American statistician and professor emeritus of biostatistics at the University of California, Berkeley.
Selvin joined the faculty of the School of Public Health at UC Berkeley in 1972, and in 1977, he became the head of its biostatistics division.
After receiving criticism for his suggested solution, Selvin wrote a follow-up letter entitled On the Monty Hall Problem, published in August of the same year.
Selvin proposed a solution based on Bayes' theorem in this second letter and explicitly outlined some assumptions concerning the moderator's behavior.
As a result, quite a few papers were published on the Monty Hall Problem over the years, and it is featured in many introductory probability & statistics classes and textbooks.
