Sarah Brown Ingersoll Cooper

Sarah Brown Ingersoll Cooper (December 12, 1835 – December 11, 1896) was an American philanthropist and educator.

Sarah Brown Ingersoll was born in Cazenovia, New York, December 12, 1835. She was the eldest of three daughters. She was educated at the Cazenovia Seminary and the Troy Female Seminary.

She met her future husband, Halsey Fenimore Cooper, at Cazenovia, and the couple were married in 1855. The couple moved to Chattanooga, Tennessee and worked as editors on The Advertiser, with Sarah assisting Halsey. They had daughters Harriet (1856) and Mollie (1861) before they were forced to flee the south at the start of the Civil War.

They briefly settled in Washington D.C., then moved to Memphis, Tennessee in 1863. In 1864, after her daughter Mollie died, Sarah began to suffer from depression and illness. For two years she attempted to recuperate in St. Paul, Minnesota, then she recovered when the family moved to San Francisco in 1869, where Halsey worked for the IRS.

At her new home, Sarah became a teacher at the Bible Class of the Calvary Presbyterian Church. She founded the Jackson Street Kindergarten Association in 1879, then went on to open the first Kindergarten in the American West.

In 1879, Halsey lost his job as Deputy Surveyor and the family suffered financial difficulties. As a result of the strain, he committed suicide in 1885. After attempting to clear her husband's name, Sarah continued her philanthropic career. She taught both the Bible School and Kindergarten, and was involved with women's rights groups. Her daughter had quit her teaching job to assist Sarah, but suffered from bouts of depression, especially following the death of her father. Harriet asphyxiated her mother and herself on December 11, 1896.
