William Thomas Ziemba was born in a small town in Western Massachusetts and became a world-renowned scholar of quantitative finance, risk control and management science. He died at home in Vancouver. He is survived by his wife, Sandra Schwartz and daughter, Rachel Ziemba…

Known as “Dr. Z,” Bill developed scenarios, models and studied anomalies across any market he could think of – from Jai alai, sports betting, currencies, equities, and horse racing, seeing all as forms of investment where decisions could be studied, optimised and bets appropriately scaled.

Bill’s love of horse racing was sparked at an early age at Saratoga racetrack. His books on racetrack betting were inspiring to many, and he even designed calculators that would help any bettor use his system. More recently, he achieved his dreams of owning race horses and spent more time in Saratoga, NY and in Lexington, Kentucky, the home of some of his favorite horse farms.
