Rosenthal Global Securities Remembers Founder and Futures Industry Pioneer Les Rosenthal

CHICAGO, Sept. 17, 2017 – Rosenthal Global Securities (RGS), a leading proprietary trading firm, remembers its founder Leslie Rosenthal after his Sept. 16 passing at the age of 84 after a brief illness:

Rosenthal spent his entire career in the futures industry and was inducted into the FIA Futures Hall of Fame in its inaugural year in 2005. He first became a member of the Chicago Board of Trade (CBOT) in 1958 and served for two terms as its Chairman beginning in 1981. He was also Chairman of the Board of Trade Clearing Corporation. He was a director of the Chicago Mercantile Exchange and MidAmerica Commodity Exchange and a founding member of the National Futures Association.

Starting his career as a trading floor runner, he worked his way up the ladder in the brokerage business and as a floor trader, founding his own brokerage firm, Rosenthal & Co., in 1970 as a CBOT clearing member. In 1982, he founded RGS as a proprietary trading firm. In 1988, he merged Rosenthal & Co. with Collins Commodities, led by J. Robert Collins. The firm traced its roots back to 1923 with the founding of Greene and Collins. Together, they became Rosenthal Collins Group.

Les Rosenthal was an early and vocal proponent of introducing financial futures contracts as well as electronic trading. He said: “Unless you do something to change with the times, you become non-existent.”
