David Dwight Baldwin (November 26, 1831 – June 16, 1912)[1] was a businessman, educator, and biologist on Maui in the Hawaiian Islands.

In 1872 Baldwin and his family lived in New Haven, Connecticut, while he worked in the Yale Law School library and earned his Master of Arts degree.

Baldwin had earlier published a list of Hawaiian mosses and liverworts (hepatic plants, or Hepaticae in Latin).

In addition, several land snail species in the family Achatinellidae were named in honor of him, as well as a subgenus Baldwinia of the genus Partulina.

[6] His schoolmate from Punahou, J. T. Gulick, had published early theories of evolution which were based on their mollusc shell collections.

The same word also referred to small bits of fish, chicken, or banana relish served with kava.

[9] Three years later, Belle Dickey, who was the niece of both a brother-in-law and a sister-in-law of Baldwin, married James Dole, who popularized Hawaiian pineapple.

After a cancer operation in February 1911, Baldwin died on June 16, 1912, at the Queen's Medical Center in Honolulu.

Son Erdman Dwight Baldwin was born December 9, 1859, married Nellie Virginia Curtis, became a Civil Engineer and died July 11, 1942.

[15] Son Benjamin Douglas Baldwin was born April 12, 1868, managed sugar plantations on Maui and Kauaʻi.

[12][16] Son William Atwater Baldwin was born July 20, 1869, became manager of three different sugar plantations and then President of Haiku Fruit & Packing Company.
