Guy Desbarats, a Canadian architect was born on July 30, 1925, in Montreal, Quebec. He studied engineering at McGill University before turning to architecture. He graduated in 1948 and started to work at the firm of architects James William Abra, James Watson Balharrie, and David Shore in Ottawa until 1952. Then he returned to McGill University as a research fellow of the Central Mortgage and Housing Corporation (Canada Mortgage and Housing Corporation) to conduct research on duplexes in Montreal.

In 1953, he founded one of Canada's most prestigious architectural firms, ARCOP (Architects in Co-partnership). As an associate architect, he collaborated on several of the firm's major projects, including the thematic pavilions L'Homme à l'oeuvre and L'Homme interroge l'Univers for Expo 67, the Beaver Lake pavilion on Mount Royal (1955-1958), the National Arts Centre (1969) in Ottawa, Salle Wilfrid-Pelletier (1963), and Place Bonaventure (1967). After the agency's dissolution in 1970, Desbarats held a few positions in the public service, notably with the Department of Public Works Canada. He was Assistant Deputy Minister of Design in 1975 and Assistant Deputy Minister of Design and Construction from 1976 to 1985. He returned to private practice in 1985 and founded Canadian Construction Information Services Limited.

Committed to the training of the next generation, Desbarats became a lecturer at McGill University in 1953 and he also set up an internship program at the Centre des métiers de la construction. In 1964, he became the first director of the new School of Architecture at Université de Montréal. In 1968, through the merger of the School and the Institut d'urbanisme, he formed the Faculté de l'aménagement and became its dean until 1975.

In 1952, he married Aileen Anne Cobban. He died on August 30, 2003, in Sherbrooke, Quebec.

Antiquarian book dealer, author, publisher, and reviewer, John Newton Mappin was born in Montreal, Quebec, Canada in 1926 and died there in 2008. Mappin lived in Montreal with his wife Judith (Judy) Taylor, who had co-founded The Double Hook, a Canadiana bookshop, while she was a student at McGill University. John Mappin took over the family jewelry business, Mappin & Webb Limited, after his father’s death. He sold the business in 1962 and entered the book trade business shortly thereafter. Mappin graduated with a Master of Arts in political science and economics from McGill University in 1968. His thesis was titled The political thought of Francis Maseres, attorney general of Canada, 1766-69.

For over 40 years, Mappin himself was a collector and dealer of antiquarian books in Montreal, as John N. Mappin Rare Books. He operated out of his home office and as thus never had a brick and mortar store, nor did he participate in book fairs. He issued book lists and met privately with his customers, many of which were libraries building their Canadiana collections.

As an author, Mappin is most known for his book Bernard Amtmann 1907-1979: a personal memoir, which has been cited multiple times in scholarly literature. Antmann was a fellow Canadian antiquarian bookseller from Montreal.

Born February 15, 1889 the daughter of Anna and Bernard J. Harrington, and raised in Montreal in a houseful of siblings beside the McGill University campus, Lois married Edward Winslow-Spragge, a young engineer, in 1912. Theirs had been a four-year courtship, detailed in their correspondence, published in 2000 by their daughter, Anne V. Byers. Lois, who signs herself “Loie” and sometimes “Sybil,” writes to “Eddy” regularly about such things as her interview in 1909 for a job teaching art at Miss Edgar's and Miss Cramp's school for girls, and how much she misses him during his train trip across Quebec, Ontario and the Northwest. His travels for his work and their longing for each other during his long absences, would be a constant theme throughout their marriage. Lois raised their five children (Alice Margaret, Edward, Anne, Ruth Naomi and Mary Lois) frequently alone in Montreal and Sherbrooke with summers in Metis at the old Dawson home, Birkenshaw, which she eventually inherited from her sister Clare. It was not until their sixties that she and her husband were finally able to live together without the continual interruptions of travel for his job. With the children grown up then, she was able to indulge her love of art (evident in the doodlings and sketched portraits in her letters), for which she had a talent like her mother, Anna, and her uncle George Mercer Dawson, both of whom have works exhibited in the McCord Museum. She also was able then to write a biography of George, entitled “No ordinary man.” Lois died in 1978 in Lanark, Ontario.
