Robert Henry Sorgenfrey (August 14, 1915 – January 7, 1996) was an American mathematician and Professor of Mathematics at the University of California, Los Angeles at UCLA until his retirement in 1979. The Sorgenfrey line and the Sorgenfrey plane are named after him; the Sorgenfrey line was the first example of a normal topological space whose product with itself is not normal.
