Developer
Developer
McDuffie is best known for developing the Claremont and Northbrae neighborhoods of Berkeley and St. Francis Wood district in San Francisco. His upscale developments were laid out as "residential parks," with streets following the contours of hills and underground power lines. Like many other developments at the time, his developments included racial covenants to exclude non-whites from home ownership, and he also promoted single-family zoning laws to exclude non-whites.
Conservationist
Conservationist
McDuffie was a notable conservationist, and was president of the Sierra Club from 1928 to 1931 and 1943–1946.

Mountaineer
Mountaineer
McDuffie was an accomplished mountaineer in the Sierra Nevada, and made first ascents of Mount Abbot and Black Kaweah. Along with Joseph N. LeConte and James S. Hutchinson, he pioneered a high mountain route in 1908 from Yosemite National Park to Kings Canyon, roughly along the route of the modern John Muir Trail. In 28 days, they completed a trip of 228 miles through the high mountains, including several previously unexplored sections. McDuffie suffered from Parkinson's disease for nearly 20 years before his death in 1951. The Sierra peak Mount McDuffie is named after him.
