Marianna Wieder van Erp, a longtime resident of Mountain View, died on Dec. 10, surrounded by her family. She was 83.
Born in Milwaukee, as a teenager she moved to Monrovia, California. She met her future husband, Dirk, at a Stanford University outing to Santa Cruz, where their fate together was sealed after a ride on the Giant Dipper together.
After graduating from Stanford and attending the social work program at the University of California, Berkeley, she raised five children. During this time she volunteered extensively, including with the Girl Scouts, at the local polling station and with the Red Cross, according to her family.
She entered the paid workforce in her early 50s, where she found a love of computers and computer teaching that stood her in good stead during a five-year stint in Seoul, South Korea in the 1980s.
She was a dedicated volunteer at the Mountain View Library, where her love of books and knowledge of the Internet combined to great effect in the second-hand bookselling fundraising effort, her family said.
She is survived by her children, William, Janna van Erp Mori, Joanne van Erp Montague and Mary van Erp Bythell; and twelve grandchildren.
She was preceeded in death by her granddaughter Kyla, her daughter Ruth van Erp, her husband of 53 years, Dirk, and her brother Thomas Wieder.
Anyone wishing to make a charitable contribution in her memory is asked to donate to either the Friends of the Mountain View Public Library (650-903-6336), where she volunteered, or to Pathway Hospice Foundation (408-730-1200), which provided such excellent care during her final hours, her family said.
