Deuce Williams was born William Henry Jasmer, Jr. on May 18, 1934, in Detroit, MI. He was an Employee of Michigan Bell Telephone Co. (later A.T. & T.). In 1954 he became a Square Dance Caller and was well known throughout the country.

Deuce quickly became very popular calling at "Sam Clark's Modern Squares Barn" located on 7 Mile Road in Livonia, MI. He also had a home club located here in Metro Detroit called "Lighted Lantern Squares" that danced at Simpson Jr. High School in Flat Rock, MI. Deuce was also an active Member of Callerlab up until 2002 when he had to quit calling due to ongoing health issues.

He wrote (authored) 27 different calls, 26 which are still in use today in the Plus, Advanced, and Challenge programs. Some of the calls he wrote include Flip the Diamond, Fan the Top, Diamond Chain Thru, Transfer and (Anything), Follow Your Neighbor.

Deuce, co-wrote along with Al Brundage and Earl Johnston a monthly caller's Note Service called News-N-Notes that was published from December 1975 - 1984.

Deuce also recorded 6 different singing call records on Top Caller Square Dance Record label. Some of the titles he recorded are Wabash Cannonball, Good Deal Lucille, Holly Jolly Christmas, Hey Good Looking.

Deuce was well-known for his great choreography, but Deuce was also known for being a "pioneer" for sight calling (how most callers put dancers back to their original corners and resolve a square).

Deuce spent the last years of his life in a nursing home in Livonia, MI where he passed away on Sept. 18, 2015. He was 81 years old.
