[4] "Nienkamper threw himself into one of Canada's most optimistic eras," writes architecture critic Lisa Rochon, "when government-sponsored design centres in Montreal, Ottawa and Toronto opened and exhibitions travelled across the country.

In this milieu, Nienkämper established his eponymous furniture company in 1968, opening a showroom at 300 King Street East in Toronto in the same year.

[12] Only a few years earlier, in 1968, Nienkämper had renovated the derelict building at the corner of King and Jarvis streets into a modern furniture showroom,[13] which was the first of its kind in Canada.

[15] Over five decades, Nienkämper has collaborated with a roster of designers and architects including Thomas Lamb, Tom Deacon, Yabu Pushelberg, Mark Müller, Scot Laughton, Karim Rashid, Shim Sutcliffe, Busk + Hertzog, Hadi Teherani, Andre Staffelbach, and many others on furniture collections.

[9] With architect Arthur Erickson, Nienkämper produced furniture for Canadian Prime Minister Pierre Trudeau’s office in Ottawa (1976); the Embassy of Canada in Washington D.C. (1989), and Roy Thomson Hall in Toronto (1982).
