Edward H. Deavitt (December 1, 1871 – October 2, 1946) was a Vermont politician, attorney and businessman who served as Vermont State Treasurer and Speaker of the Vermont House of Representatives.
Edward Harrington Deavitt was born in Moretown, Vermont on December 1, 1871. He was raised in Montpelier, graduated from the University of Vermont in 1893, received a law degree from Harvard Law School in 1896 and became an attorney, first in Boston, Massachusetts, and later in Montpelier.
In addition to practicing law Deavitt was involved in several businesses, including serving on the boards of directors of several banks and local utilities and an executive of a Montpelier granite manufacturing company.
A Republican, Deavitt served as a member of the state board of bar examiners and a bankruptcy referee in the late 1890s and early 1900s. In 1906 Deavitt was the successful candidate for State Treasurer, and served until 1915.
In the mid-1920s Deavitt served as an aide to Governor Franklin S. Billings before resigning to become the state Commissioner of Finance.
Deavitt served as a member of Montpelier's City Council from 1923 to 1926, and Mayor of Montpelier from 1926 to 1930.
In 1928 Deavitt ran unsuccessfully in the Republican primary election for Governor of Vermont. Incumbent John E. Weeks ran successfully for reelection, arguing that the Vermont Republican party's "Mountain Rule" limiting governors to two years in office should not apply because Weeks was best able to lead the state's recovery from the great flood of 1927. Political observers regarded Deavitt's challenge to Weeks as a half-hearted effort to maintain the Mountain Rule.
