for the last time, at the Park Arena in Bridgeport, Connecticut losing in a ten-round points decision. Silverberg could not manage the speedy attack of Wolgast. The two contenders had previously met in important non-title bouts on March 10 and May 8, 1930, in Queens, N. Y., and Philadelphia, Pennsylvania where Silverberg lost in 10 and 8 round points decisions. In March 1930, Wolgast had impressively taken the NYSAC World Flyweight Title against Black Bill at Madison Square Garden. He clinched the title in May 1930 against Willie LeMorte. Several boxing websites rated Wolgast the eighth greatest flyweight of all time. Life after boxing Silverberg won his last known fight, a four rounder against Frankie Reese at Star Casino in New York. After his retirement from the ring, he stayed in touch with boxing and promoted fights, refereed local bouts, and coached ring science as a volunteer at a local YMCA in the 1940s. In the fall of 1950, Silverberg was the subject of legal prosecution and conviction for the entertainment provided at a large gala held at his newly opened gymnasium in Ansonia. Silverberg was known in Ansonia for his campaign work in a local mayoral election. By the early 1950s Silverberg was working as an inspector for aircraft engines at AVCO Lycoming in Stratford, Connecticut near his hometown of Ansonia. He fought in the Connecticut area and lived in Ansonia during much of his early life and career. Silverberg recovered from a heart attack in 1959, though it was not his first. He died at his home in Ansonia on January 16, 1964, after another heart attack at the age of 59. He was survived by his wife and two children, Janis, and Ron. Prior to the year 2000, Silverberg's boxing achievements were given little or no coverage by on-line boxing sites, and published boxing histories.
