The Glasgow-born designer and architect honed his skills at evening classes in art and design at the school, before going on to pioneer the distinctive "Glasgow Style" that characterises works including the Scotland Street school, the Willow Tearooms, and the original Herald building in Mitchell Street.
Other famous alumni also include the photographer Harry Benson, known for his portraits of US presidents and celebrities such as Elizabeth Taylor and Michael Jackson, and the latest Scot to take on the role of Dr Who, Peter Capaldi.
Capaldi, who during his time as an art student in the 1970s also fronted a punk rock band whose drummer Craig Ferguson became a comedian and then a US talkshow host, is not the only actor to have graduated from the school.
Cracker star Robbie Coltrane also counts it as his former stomping ground, as does playwright and Makar Liz Lochhead.
Painters Alasdair Gray, whose murals decorate parts of Glasgow's subway network, and Peter Howson, whose artwork features on Alex Salmond's official Christmas card this year, are among its most famous former students.
