Biographical notes

On January 12th, 1879, Alfred Dennis (A.D.) Thacker was born in Walsall, a county of Staffordshire, England, to father Richard Edgar Thacker and mother Emma (née Fox) Thacker.He immigrated to Canada in 1910, after receiving his initial training as an architect in Birmingham.Thacker was married to Constance Margaret Ritchie two years after he arrived in Canada, on June 5th, 1912. They had one son and two daughters.

While living in Canada, Thacker worked with many firms in Montreal and Toronto. He was first employed with Ross and Macfarlane (now Ross and MacDonald) in Montreal before moving on to Chapman and McGiffen in Toronto, and then returning to Montreal to work with McVicar and Heriot, Brown and Vallance, and David R. Brown. Thacker began his own practice in 1926 and subsequently designed many churches and private homes.

Thacker designed a church on the First Nations reserve Kanawá:ke around 1928 for the newly formed United Church of Canada. The United Church, and many other religious institutions, were directly involved in the colonization and oppression of Indigenous Peoples across the continent.[1] These policies and systems were mandated by the federal government in Canada and carried out by religious institutions. This church project, which operated a school that’s been recognized by the Canadian government as being part of the Federal Indian Day School system [2], represents Thacker’s involvement in these systems.

Thacker also designed churches for the United Church in Hampstead and Dundee in Quebec, and a church for the Christian Science Church in Côtes-des-neiges in Montreal. His designs for the new choir stalls and chancel furniture in the All Saints Cathedral in Halifax were awarded an Honorary Mention from the Royal Architectural Institute of Canada.

Alfred Dennis Thacker passed away on September 26th, 1938 and was buried in Chambly Quebec.
