Sid Addelman began his athletic career in 1948 at the age of 16, playing in the Jewish Boys’ Softball League (JBSL). The following year, his team, managed by Joe Osterer, won the league championship. Around the same time, he also played baseball in the competitive Mercantile League for St. Anthony’s and in the YMCA League from 1949 to 1950.

While attending Lisgar Collegiate, Sid excelled in multiple sports. He was captain of the basketball team and was selected to represent Ottawa in football at the Red Feather Tournament, a prestigious national competition featuring top teams from across Canada.

During the early 1950s, as a student at Carleton University, Sid became a standout player on the Ravens’ basketball team. His height and natural athletic ability often made him the league’s top scorer, earning him the Doug Banton Memorial Trophy as the league’s Most Valuable Player (M.V.P.) in the 1953-54 season. While at Carleton, he also took up table tennis and quickly became the university’s champion for two consecutive years.

After graduating from Carleton in 1954, Sid continued his studies at the University of Delaware, where he discovered volleyball and became a key player on the school’s team, competing in tournaments in New York and Philadelphia. His athletic involvement extended to tennis, squash, racquetball, and bowling, where he maintained an impressive 180 average.

Beyond his personal athletic achievements, Sid was dedicated to fostering youth sports. As a professor of statistics in Buffalo, New York, he played a crucial role in organizing little league baseball, junior football, and ponytail baseball, continuing the legacy of his father, Percy, who was also deeply involved in sports.

Alongside his athletic career, Sid excelled academically. He earned a master’s degree in Mathematics at the University of Delaware and a Ph.D. in Statistics at the University of Iowa. He became a full professor at the State University of New York and later served as Chairman of the Department of Statistics. In 1968, he was elected a Fellow of the American Statistical Association (A.S.A.) and served as editor of the A.S.A. Journal for many years.

Sid passed away in 1979 after a battle with cancer, leaving behind an enduring legacy of excellence in both athletics and academics, of which his family and community remain immensely proud.
