William Currie Colket

On behalf of SIGAda, we regret to announce the passing of Mr. William Currie Colket, a staunch supporter of the Ada Programming Language and especially the Ada Semantic Interface Specification (ASIS). He passed away on December 23, 2015, in Idaho, surrounded by family.

Currie served as Chair of SIGAda from 1997 to 2000 and as Chair of the ASIS Working Group (ASISWG), overseeing the development of ASIS into an International Standard. He was a personal friend of mine even during retirement and continued to invite friends of Ada into his home in Bradenton, Florida, when SIGAda held its conference in Tampa Bay in 2009. Indeed, he will be remembered...Clyde Roby.
