Fred Dayton Lambert

Fred Dayton Lambert (28 October 1871 — 21 February 1931) was an American botanist and educator.

Lambert was born on October 28, 1871, in Muscatine, Iowa, to Daniel Meader and Ellen née Scudder. He grew up on the banks of the Mississippi, hunting, fishing, swimming, and building rafts. 

Lambert obtained a bachelor's degree in biology from Tufts University, Massachusetts, in 1894. He continued his studies at Tufts while he served as an assistant in the biology department, receiving both his M.A. and his Ph. D. degrees in 1897. 

As an undergraduate, he was a member of the football and track teams, Delta Tau Delta fraternity, and Phi Beta Kappa.

In 1899, Lambert returned to Tufts as an instructor of natural history. The following year, he became an assistant professor of biology. He remained at Tufts for the rest of his life, except in 1910-1911, during which he studied at the University of Freiburg, Germany, and at Naples Zoological Station.

In 1904, he became an assistant professor of botany, and by 1915, he was a full professor of botany. 

Lambert was also involved in the creation of the college's biological station in South Harpswell, finding for it a suitable location and taking students there for several years before it was moved and became the Mt. Desert Island Biological Laboratory.

Lambert married Mary Anna Ingalis on June 6, 1903. They had one daughter, Elizabeth. 

Lambert died on February 21, 1931, at the age of 59.
