Frank Nicholas Meyer (1875-1918) was born in Amsterdam, began his career at the Amsterdam Botanical Garden where he worked his way up to the position of head gardener in charge of the experimental garden. His aptitude caught the attention of Hugo de Vries (1848-1935), who became his mentor.
Meyer arrived in America in 1901, and obtained work with the United States Department of Agriculture (USDA). After a year with the USDA, he went to Mexico to collect plants. On his return in 1904, David Fairchild (1869-1954) of the Foreign Plant Introduction Section of the USDA hired Meyer to make a collecting trip to China. When Meyer sailed for China in 1905, he began a 13-year odyssey that led to the introduction of more than 2,000 species of plants. In an arrangement between Charles S. Sargent and Fairchild, Meyer sent the Arnold Arboretum trees and shrubs of ornamental value along with his photographs of plants and landscapes.
