Duncan McDuffie

Duncan McDuffie (September 24, 1877 – 1951) was a real estate developer, conservationist, and mountaineer based in Berkeley, California, United States.

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.

In 1934 McDuffie helped create the East Bay Regional Park District in the Berkeley Hills.

McDuffie was an accomplished mountaineer in the Sierra Nevada, and made first ascents of Mount Abbot and Black Kaweah.
