Mr. Lehane, 66, was struck by a train April 7, and his death has been ruled a suicide, said San Mateo County coroner Robert Foucrault.
Mr. Lehane "dedicated his life to making the world a better place for children," and worked for various childhood development nonprofits, according to a paid obituary that ran in the Sunday editions of the San Francisco Chronicle and San Jose Mercury News.
He is survived by his wife, Mary Puglisi; his three children, Christopher, Erik, and Erin Lehane; and five grandchildren. He previously served as director of the Avant! Foundation, according to the obituary.
Mr. Lehane reportedly stepped out of a grove of trees onto the train tracks between Encinal and Glenwood avenues in Menlo Park at about 8:38 a.m., said Lt. J. David Triolo of the San Mateo County Sheriff's Office's transit police bureau.
He was struck and killed by southbound Caltrain Baby Bullet train No. 322, said Caltrain spokeswoman Christine Dunn. There is no pedestrian crossing in the area, she said.
It was the fourth fatality on the Caltrain tracks this year, Ms. Dunn reported.
In lieu of flowers, donations may be sent to the Stephen F. Lehane Memorial Fund, 3184 Washington St., San Francisco, CA, 94115.
The fund was created to honor Mr. Lehane's support of disadvantaged children, according to the obituary.
