Margery Mastbaum "Peggy" Solomon (1909 - March 4, 1995) was an American bridge player from Philadelphia, Pennsylvania. She also played under the name Peggy Golder. As Golder in 1942, she became ACBL Life Master number 33, the third woman to achieve the rank after Sally Young and Helen Sobel.
Solomon was the daughter of Jules Mastbaum, a Philadelphia real estate investor who specialized in movie theaters and the philanthropist whose estate established that city's Rodin Museum. Both parents played bridge. In 1930 she married Benjamin M. Golder, who was a U.S. Congressman from Philadelphia (1925-1933); he would be 1946 president of the American Contract Bridge League (ACBL) and die in office. Peggy Golder started bridge lessons "shortly before World War II". Charles Goren was her second teacher and Charles J. Solomon, another star player from Philadelphia became her mentor; they married in 1948. Charles Solomon would be president of the ACBL in 1958, the year the World Bridge Federation was established, and second president of the WBF (1964-68). He died in 1975.
Solomon died at age 86, at home in Elkins Park, on March 4, 1995. According to a daughter the cause was pulmonary fibrosis. She was survived by a sister, two daughters, eight grandchildren and eight great-grandchildren.
Solomon played in one world championship tournament, the fourth quadrennial World Team Olympiad in 1972. She was a member of the 6-person USA women team that finished third behind Italy and South Africa. With Gail Moss instead of Solomon the team would win bronze and gold medals in 1976 and 1980.
In ACBL competition Solomon won one national-level tournament in the open category, the 1944 Chicago Board-a-Match Teams (now the North America-level Reisinger). She won the premier national championship for women pairs (Whitehead Women's Pairs) in 1945 with Olive Peterson and in 1960 with Mary Jane Farrell. She won the analogous tournament for women teams five times from 1942 to 1970 and that for mixed teams three times.
