Mary Clark Thompson

Mary Clark Thompson (1835 – July 28, 1923), born Mary Lee Clark, was an American philanthropist and wife of banker Frederick Ferris Thompson.

Early years

Mary Lee Clark was born in Naples, New York, in 1835 to Myron Holley Clark (1806–1892) and Zilpha (née Watkins) Clark (1806–1877). She moved with her family to Canandaigua, New York, when she was about two years old.

She attended various schools in Ontario County, including the Ontario Female Seminary. Mary's father Myron was elected Governor of New York State in 1855, and the family took up residence in Albany, the state's capital. and a great benefactor to the Bronx Zoo and Woman's Hospital.

Her husband died in 1899 at age 62 in New York City, and Mary continued to make Sonnenberg her summer home. She continued to give generously to civic, religious, and educational institutions, though her philanthropic work focused principally on the community in which she lived. In Canandaigua, she established and built the F.F. Thompson Hospital in 1903 and the Woodlawn Cemetery chapel, and a swimming school on the shore of Canandaigua Lake. She established a retirement home which she named Clark Manor House after her parents. She donated land and money for the city's post office, and contributed heavily to the local Ontario County historical society, the Wood Library, and numerous local churches.

She had an interest in preserving the history of Native Americans in the New York area, and made multiple contributions to the State Museum in Albany for that purpose.

Although the Thompson's principal residence was at 283 Madison Avenue in New York City, the couple spent their summers in Mary's girlhood home of Canandaigua on an estate they purchased in 1863. The estate was named Sonnenberg (means "sunny hill" in German) when they purchased it. In 1885, they tore down the farmhouse and replaced it with a 40-room Queen-Anne style mansion.

Honors and legacy In 1920 she was awarded the Cornplanter Medal for her work in Native American history.

Her home, Sonnenberg, is preserved and operated as a historic house museum.

The Mary Clark Thompson Medal is named for her. It has been awarded since 1921 by the American National Academy of Sciences for work in geology and paleontology.
