Dudley Whitney Adams (November 30, 1831 in Winchendon, Worcester County, Massachusetts – February 13, 1897 in Tangerine, Florida) was a horticulturalist and a leader in the Granger movement.
Dudley became a teacher as a young man and, at age 21, traveled west and became one of the first settlers of Waukon, Allamakee County, Iowa.
He headed the first attempt to legislate railroad freight and aided in framing proposals for fixing rates and outlawing discrimination on that basis.
He was also appointed to a committee to publish a booklet about Orange County for distribution at the Cotton States and International Exposition in Atlanta in 1895.
Adams was married January 31, 1856 at Winchendon, Massachusetts, to Hannah Heustis, a native of Yarmouth, Nova Scotia, Canada.
