Alfred Rehder was born in Saxony to the gardener of a duke's estate. Rehder worked at major German botanical collections until his early 30's, when he was sent to North America in 1898 at the age of 34. Rehder soon came to attention of Liberty Hyde Bailey, who wrote works on North American horticulture, to which Rehder contributed major chapters. By 1911, he was working with Charles S. Sargent of Harvard University, compiling a bibliography of botanical works from around the world. With Wilson, Rehder described many Asian species that were first described botanically and imported to North America in the first two decades of the 20th century in Plantae Wilsonianae. In 1918 Rehder was appointed curator of Harvard University's Arnold Arboretum.
