Condolences sent for the passing away of co-creator of Duckworth-Lewis-Stern method Tony Lewis
Bangladesh Cricket Board(BCB):
The Bangladesh Cricket Board (BCB) expresses deep sadness at the passing away of mathematician and statistician Tony Lewis, co-creator of what is now known as the Duckworth-Lewis-Stern (DLS) method for deciding weather-affected limited-overs matches. Lewis was 78.
Offering his tribute, BCB CEO Nizam Uddin Chowdhury said: “Tony Lewis revolutionised the game of cricket with a method that is considered the fairest in settling weather-interrupted games. His contribution will be forever remembered.”
Lewis and fellow statistician Frank Duckworth had co-devised the system originally called the Duckworth-Lewis method which was first used in 1997 and officially endorsed by the International Cricket Council (ICC) in 1999. The system calculates targets based on the batting team's wickets in hand, and overs in hand via mathematical formulas. In 2014, Professor Steven Stern of Australia’s Bond University became the custodian of the system following the retirements of Duckworth and Lewis.
International Cricket Council (ICC):
The International Cricket Council (ICC) has expressed its sadness at the death of mathematician Tony Lewis, who co-developed the Duckworth-Lewis-Stern system of calculating target scores in rain-affected limited-overs matches.
Lewis, who passed away at the age of 78, had developed the original Duckworth-Lewis method jointly with Frank Duckworth, which was adopted by the ICC in 1999. After the retirements of Duckworth and Lewis, Steven Stern became the custodian of the method and his name was added to the system in 2014.
Geoff Allardice, ICC General Manager – Cricket: "Tony’s contribution to cricket is huge. The present day system of resetting targets in international cricket is based on the one developed by him and Frank more than two decades ago.
"His contribution to the game of cricket will be remembered for years to come and we send our condolences to his family and friends."
Lewis, a graduate in mathematics and statistics from Sheffield University, retired as a lecturer of Quantitative Research Methods from Oxford Brookes University. He was appointed a Member of the Order of the British Empire (MBE) in 2010.
