## Early life

Mai Arbegast was born in San Jose, California in 1922, the oldest of six children. Her father, Gijiu Kitazawa, and uncle started the Kitazawa Seed Company and nursery in 1917. When they split the business, Gijiu moved the seed operation to a downtown San Jose storefront and sold seeds wholesale and retail, adding his own line of Asian vegetables. The Kitazawa Seed Company became the main seed source for Japanese tenant farmers in California and Oregon. In an interview with Margaret Schulze for NikkeiWest Mai recalled, “I spent much of my early life in boots stomping on particular tomatoes and collecting the seed for further crosses.”

## Education

Arbegast attended San Jose State College until 1942 when her family was evicted and sent to the Heart Mountain Relocation Center in Wyoming. The family got a sponsor and clearance to move to Michigan until World War II ended while Mai attended Oberlin College, graduating in 1945. She went on to Cornell University where she was "the only woman around as a graduate student in Horticulture from 1947-49." She graduated from Cornell with a Master of Science in Ornamental Horticulture. She later went on to the University of California, Berkeley where both she and her husband, David Arbegast, graduated with Masters of Science in Landscape Architecture in 1953.

## Career

Following graduation, she began teaching in the Department of Landscape Architecture at Berkeley. She taught both full and part-time and her classes covered plant materials, horticulture, and planting design. She often took her students to the nearby Blake Estate for field study. Arbegast played a key role in the gift of Blake Garden to the UC Berkeley Department of Landscape Architecture and was its first acting director after the transfer in 1957. While teaching she also maintained a part-time professional practice. In 1967, she gave up teaching to practice full-time and continued through 2003.
