Guyana and West Indies Cricket Umpire Clyde Rory Duncan began his international umpiring career in 1988 when he umpired in a One-Day International between Pakistan and West Indies at Bourda. He umpired in a total of 21 One-Day Internationals, 2 Test matches at Bourda in 1991 and 1994, and 6 T20 Internationals. His last international match was a T20 International between West Indies and South Africa in Antigua in 2010.
Clyde Duncan was also an accomplished administrator in the local and regional Umpires Association. He served as Secretary of the Cricket World Cup Operations in the Guyana leg of the ICC World Cup Tournament of 2007. Always well-dressed, he was a school teacher and principal, and proud resident of Vreed-en-Hoop, a town at the mouth of the Demerara River, opposite Georgetown.
On 27 July 2011 Clyde Duncan died unexpectedly in Trinidad and Tobago at age 57, while undergoing treatment for cancer. He will be remembered as a humble gentleman and true professional who carried out his duties without fear or favour and was always willing to assist other umpires.
He left behind his wife Fay and children Dr. Tracey Duncan-Clarke, Joanna, Troy and Susanna, and a lasting legacy in the cricket umpiring in Guyana.
