Adelaide Thompson Williams White

Adelaide Thompson Williams White (September 1864 – July 7, 1917) was an American suffragist.

Adelaide Thompson Williams White was born in September 1864 in Dunkirk, Chautauqua County, New York, the fifth child of Julien Taintor Williams (1828–1905) and Julia King Thompson Williams (1830–1923). Her family was one of the earliest pioneer families of Chautauqua County. She had four sisters: Henrietta “Ella” Clark Williams, Jessie Carlisle Williams, Mabel Walton Williams (1866-1946), and Geraldine Williams (1860-1867).

White attended Dunkirk Union schools and followed her sister Jessie to Vassar College in Dutchess County, New York.

After her marriage with Harry Draper White on November 12, 1904, the family resided in Rome, New York.

In 1913, the Congressional Union, later the National Woman's Party (CU/NWP) was founded by women's rights activists Alice Paul and Lucy Burns to fight for women's suffrage. Paul and Burns left the much larger National American Woman Suffrage Association as a result of disagreements about tactics and strategy, including the Shafroth-Palmer Amendment. That amendment would require any state with more than 8% signing an initiative petition to hold a state referendum on suffrage. Paul and Burns felt that this amendment was a lethal distraction from their ultimate goal of an all-encompassing federal amendment providing voting rights for all American women.

While in Rome, New York, White with Lucy Carlile Watson (founder of the Utica Political Equality Club) and Glendolen T. Bens (1878–1928), also of Utica helped solicit money for the National Woman's Party. Although they did not picket, they were part of a 50-member area women's group supporting Alice Paul and her efforts to secure the vote.

The September 1, 1914, issue of the Rome Daily Sentinel reported that the Political Equality Club of Rome, New York, held its first meeting the previous day. White was the first president of the local organization. 

On November 12, 1904, Adelaide married Dr. Harry Draper White (1865–1954,) a medical doctor and president of the staff of Rome Hospital, the son of Henry Kirke White and Mary Bullard Draper. They had a daughter, Julia White Dyett (1907–1968).

White died on July 7, 1917, in Rome, New York, at the age of 52.
