Isaac Logart was a welterweight contender during the mid to late 1950s.
Among the boxers Logart fought were Joe Brown, Virgil Akins, Gil Turner, Gaspar Ortega, Yama Bahama, Don Jordan, Rudell Stitch, Luis Manuel Rodriguez, Emile Griffith, Nino Benvenuti, Garland (Rip) Randall, Stan Harrington, and Sandro Mazzinghi.
On March 21, 1958, Logart faced Virgil Akins in the semifinals of the welterweight elimination tournament. The winner would face Vince Martinez for the vacant World Welterweight Championship . Logart, who split two fights with Akins in 1955, was a 7-5 favorite. However, Akins defeated Logart by sixth-round knockout. Three months later, Akins knocked out Martinez in four rounds to win the vacant title.
Logart fell from the rankings after four consecutive losses in 1959. He eventually became a capable trial horse for aspiring welterweights and middleweights before retiring in 1966.
After his boxing career ended, Logart resided in New York City, where he died at age 55 in 1988.
