Cornelia Hahn Oberlander , (20 June 1921 – 22 May 2021) was a Canadian landscape architect. During her career she contributed to the designs of many high-profile buildings in both Canada and the United States, including Robson Square and the adjoining Law Courts Complex in Vancouver, the National Gallery of Canada, the Canadian Chancery in Washington D.C., Vancouver's Library Square, the Museum of Anthropology at the University of British Columbia, and the Northwest Territories Legislative Assembly Building in Yellowknife.

Early life and education Cornelia Hahn was born at Muelheim-Ruhr, Germany, the eldest of two daughters of Beate Hahn (née Jastrow) and Franz Hahn, who died in a skiing accident in 1933. Cornelia's uncle was educator Kurt Hahn, the founder of Schule Schloss Salem in Germany, Gordonstoun in Scotland, and UWC Atlantic College in Wales. Her aunt Elisabeth Jastrow, was a well-known archaeologist.

A horticulturist who wrote gardening books for children, Beate fostered in her daughter a deep love and appreciation for nature; Cornelia had her own vegetable garden at age four.Prominent Canadian Landscape Architect To Speak At U.Va. School Of Architecture , University of Virginia News, 9 March 2001, retrieved 2 July 2010. In an interview with Mechtild Manus, Oberlander said: "At the age of eleven... I studied a mural in the artist's studio showing the river Rhine and an imaginary town. When I asked the artist about the green spaces in this mural, she told me that these were parks. When I came home, I told my mother 'I want to make parks'. From there all my education was directed towards becoming a landscape architect."

The Hahns were Jewish. When Cornelia was 18, with her mother and sister Charlotte, she escaped Nazi persecution after Kristallnacht by fleeing to England. They emigrated to the United States in 1939, and settled first in New York, then in New Hampshire, where her mother created a truck farm."Acclaimed landscape architect's Oral History", The Cultural Landscape Foundation 3–5 August 2008. Cornelia attended Smith College, graduating in 1944 with a BA. She then went to the Graduate School of Design at Harvard University, where she studied under Walter Gropius and, in 1947, became one of first to earn a degree in Landscape Architecture."Acclaimed landscape architect honored", Smith e-news June 2006. At a class picnic, she met architect Peter Oberlander. Born in Vienna, he too had fled with his family from the Nazis in 1938 and had earned a PhD in Regional planning from Harvard. They married in 1953 and moved to Vancouver where, at the University of British Columbia (UBC), Peter became Canada's first professor of Urban and Regional Planning.

Career In 1950, Oberlander was hired as a community planner with the Citizen's Council on City Planning in Philadelphia. From 1951 to 1953, she worked for architects Louis Kahn and Oscar Stonorov, and landscape architect Dan Kiley, in Philadelphia where, for the Mill Creek Public Housing Project, she designed her first playground. She worked for in Vermont then, in Vancouver, founded her own firm, Cornelia Hahn Oberlander Landscape Architects. Oberlander then became interested in the modern art movement led by B. C. Binning and Ned Pratt, which combined art and architecture to address the connections between urbanism and surrounding natural settings.

While she completed many private gardens, the early years of Oberlander's practice were mostly dedicated to designing playgrounds and landscapes for low-income housing projects; over the course of her career, she designed 70 playgrounds in Canada, including the Canadian Pavilion's Children's Creative Centre at Expo 67 in Montreal.Cornelia Hahn Oberlander Fonds Retrieved 14 April 2020. All of her playgrounds had vegetable gardens and picnic areas; in the case of Vancouver's Skeena Terrace, she included play sculptures of her own design. Throughout her career, she conducted significant research into pediatry and pedagogy, and children's interests and activities, and urged city planners and developers to recognize playgrounds as important sites for childhood development and to include them in new construction. She emphasized the social benefits generated by free play and independent discovery, and provided practical proposals for the formulation of new playgrounds. In 1974, she was a member of the National Task Force on Children's Play established by the Canadian Council of Child and Youth Advocates. In 2022, her research was gathered into the Concordia University publication Cornelia Hahn Oberlander on Pedagogical Playgrounds.

She later practiced on a more commercial scale, working with architects and other professionals from various disciplines to create aesthetic solutions for challenging projects. Before beginning a project she researched it thoroughly to ensure that her innovative schemes would be practical and long-lasting. Sometimes, her innovations needed no research at all. In 1964, she discovered that, when orphaned tree logs washed up on Vancouver's shores, the city was burning them—Oberlander quickly convinced the city to keep the logs for seating and shelter, a practice which was immediately adopted and is now standard. She always approached a project from an environmental standpoint. In her Convocation Address for the acceptance of an honorary degree from Simon Fraser University she stated: "I dream of Green Cities with Green Buildings where rural and urban activities live in harmony... "Achieving a fit" between the built form and the land has been my dictum. This can only be done if all our design-related professions collaborate and thereby demonstrate co-operatively their relevance in meeting the enormous developmental challenges facing our increasingly crowded urban regions."SFU honorary degree recipients' convocation addresses

Oberlander's concern for the environment and for people in general, was further exemplified by her involvement with the Hebrew University of Jerusalem on Mount Scopus. Oberlander and her husband, Peter, visited Israel for a congress with the International Federation of Landscape Architects in 1962. According to the Jewish Independent, the Oberlanders were in Israel to study irrigation systems, but they "fell more deeply in love with the land and its people". The Oberlanders engaged in and spearheaded many activities to benefit the university from 1979 on, including: setting up a Canadian Studies Program, bringing boxes of Canadian textbooks to Israel for donation to the university, developing a botanical garden, working with a team of planners to assist the community of Ashkalon in accommodating settlers from North Africa and Georgia, and advocating for the restoration of historic buildings on the campus. The Oberlanders were honored for their contributions by the Vancouver chapter of Canadian Friends of the Hebrew University of Jerusalem in 2004 and they visited Israel many times in their philanthropic efforts.

Oberlander received the "rare and exceptional honour" of being elected to both the Canadian Society of Landscape Architects' College of Fellows (in 1981) and the American Society of Landscape Architects' Council of Fellows (in 1992).

In 1999–2000, she contributed her expertise to the Vancouver Art Gallery for its "Out of This Century" exhibition, guiding patrons through the selection of visual art pieces that were chosen from the permanent collection of the gallery (by Oberlander and five other Vancouverites) to reflect and represent the city art scene through the decades. In 2018, she completed a redesign of the National Gallery of Canada's Fred & Elizabeth Fountain Garden Court. She also had designed its predecessor.
