Simonson was born into a wealthy family. His father Leo was a successful wigmaker to the Manhattan rich and the theatre and movie businesses. His mother Irene was from the family that owned the Illinois Watch Case Co. in Elgin, Illinois.
He was one of the strongest American players of the 1930s, and was part of the American team which won the gold medals at the 1933 Chess Olympiad. Simonson was certainly at least of International Master strength, based on his limited playing career.
Simonson showed precocious skill with chess, soon after learning the game. At New York 1933, he scored 7/10 to tie for 2nd-3rd places, behind only winner Reuben Fine. This earned him selection to the United States chess Olympiad team at age 18. In the Olympiad, at Folkestone 1933, he played on the first reserve board and scored 3/6, as the Americans won the team gold medals. Simonson's teammates were Fine, Isaac Kashdan, Arthur William Dake, and Frank Marshall, who all eventually became Grandmasters.
In the first modern U.S. Chess Championship, New York City 1936, Simonson placed second with 11/15, behind only winner Samuel Reshevsky. In the same year he tied with Alexander Kevitz for 1st place in the 1936 Manhattan Chess Club championship, but lost on tiebreak. He tied with Isaac Kashdan in the 1937 Manhattan Chess Club championship, but lost the playoff. He scored 11/16 in the 1938 United States Championship at New York, to finish third, behind Reshevsky and Fine. In the United States Championship of 1940, again at New York, he tied for 4th-5th places, with 10/16, behind Reshevsky, Fine, and Isaac Kashdan. Simonson defeated Reshevsky in a Metropolitan League team match in 1950, at a time when Reshevsky was among the world's top five players. Simonson was ranked sixth in the country on the very first official rating list, issued in 1950, from the United States Chess Federation.
According to his close friend, Grandmaster Arnold Denker, from the acclaimed book by Denker and Larry Parr -- The Bobby Fischer I Knew And Other Stories—Simonson was very skilled at indoor card and board games, but had a serious gambling problem. He was married three times, and fathered three children.
He died in San Juan, Puerto Rico.
