Among them was Napa resident Edith Oto, who coincidentally also is celebrating her 90th birthday on the same day.
She was a nursing student in 1942, when her family was sent to an internment camp.
Even without a degree, she became the camp's nurse, then later earned her degree and spent a career in nursing.
Only eight students in the 1942 class are still living.
Four, including Edith, attended the day's ceremony.
