Marguerite Porter was born in 1904 in
Pleasant Valley, Nova Scotia. She studied painting at the
Nova Scotia College of Art, and also traveled to the United States to study privately with German-American abstract expressionist painter
Hans Hofmann. In 1928, as a senior student at the Nova Scotia College of Art, Porter had one of her etchings accepted by the
Society of Canadian Painters, Etchers and Engravers. That same year, she began teaching classes at the College, earning an annual salary of $600 for the next two years. Zwicker taught painting at
Acadia University in
Wolfville and eventually led "painting and cultural tours" in countries such as Spain, Italy and Portugal. and she exhibited her work at the
Royal Canadian Academy of Arts and the Art Association of Montreal. Zwicker was a member of the Nova Scotia Society of Artists. Zwicker's Gallery had been established in 1886 by a member of Leroy's family, and up until the 1970s it was the only gallery in Halifax that routinely held art exhibits open to the public; the gallery was a valuable outlet for local artists. The Zwickers continued to operate the gallery themselves until 1968, after which it passed into new ownership. In 1991, Zwicker held a solo exhibit of her work at the Art Gallery of Nova Scotia. Zwicker died in 1993 in Halifax. == Education ==
