Dr. Robert Leif, one of SIGAda's hardest working volunteers, passed away on August 3, 2020; he was 82 years old. After gaining he Ph.D., he worked and taught at several companies and universities in Florida. While at Coulter Corporation, Bob was an early adopter of the Ada programming language and foresaw many of the modern digital information products used by the medical industry. He was always a strong proponent of open standards which was one reason he became involved with the Ada programming language. After his family's move to the San Diego area, Bob became involved with the local SIGAda organization. He was a former chair of San Diego SIGAda and served as the Conference Chair for SIGAda 2003 held in San Diego.
