Herbert Maurice John Prins, distinguished architect, professional conservation and heritage architect and practitioner passed away on Wednesday, 15th April 2020, just 12 days short of his 93rd birthday. His was a long, rich and remarkably productive life. Herbert was a role model in his work and ongoing commitment to the heritage of Johannesburg and other parts of South Africa until just a couple of months before his death. It was a joy to celebrate his 90th birthday in 2017. His professional career extended over 72 years - surely a record.
