Eberhard Heinrich Zeidler, (January 11, 1926 – January 7, 2022) was a German-Canadian architect. He designed iconic structures and landmarks in Canada and internationally, most notably in Toronto. These included the Toronto Eaton Centre, Ontario Place, Toronto Centre for the Arts, as well as redevelopments of the Queen's Quay Terminal and the Gladstone Hotel. His firm also designed Canada Place in Vancouver for Expo 86. Early life Zeidler was born in Braunsdorf, Germany, on January 11, 1926. He served in the German navy during World War II. He was instructed under the influence of the Bauhaus school in Weimar and the Technische Hochschule Karlsruhe. He fled East Germany and worked in the office established by Emanuel Lindner, his former professor. There, he constructed several factories and medical buildings. Zeidler subsequently immigrated to Canada in 1951. Career Zeidler first joined an architectural firm with Blackwell and Craig in Peterborough, Ontario. He later relocated to Toronto in 1963 and worked for the firm became Craig, Zeidler and Strong until 1975. One of the essential elements of his early works is his employment of striking interior atrium space, which became widespread on an international level during the 1970s. Moreover, his experience in the Bauhaus school made him familiar with the technological matters in building design. These included structural and mechanical services (most notably, exposed air-handling ducts), as well as aspects that ease movement and communication. This was exemplified in the McMaster University Health Science Centre, his breakthrough project, which was meant to resemble a large construction set for children. The building utilized regular geometric building modules, coupled with glazed service and circulation towers, internally exposed steel trusses, ducts, and an automated materials delivery system. Most of Zeidler's structures were public buildings. He envisaged Toronto Eaton Centre – which opened on February 10, 1977 – to be an "interior street" instead of being simply a shopping mall. Two of the structures his firm designed for the University of Maryland Medical System in Baltimore were meant to connect the passing from the 20th to the 21st century. His later projects incorporated elements pertaining to sustainable development. For instance, the Student Learning Centre at Ryerson University (2015) featured a green roof and energy efficient lighting on the exterior. Likewise, The Bow in downtown Calgary employed an energy efficient glass facade, interior atria, and roof gardens. Zeidler rarely designed private residences, drawing up approximately 20 in his
