To some of his former students, Professor Barry Dwolatzky was the “Grand Geek” – a name of which he was very proud. But Barry, who passed away in Johannesburg, South Africa on 16 May 2023, was much more than a computer geek. He was also a leader and a visionary in the field of software engineering in South Africa. At the time of his passing he was 71 years old. He was by then retired from academia and held the title of Emeritus Professor at the University of the Witwatersrand (Wits), where he spent much of his career.
