Charles Alfred Weatherby (1875–1949) was a botanist.
Weatherby was born in Hartford, Connecticut to Charles Nathaniel Weatherby and his wife the former Grace Weld. Not long after Charles Alfred's birth the family moved to Colorado. However when he reached school age his parents sent him back to Connecticut.
Weatherby studied literature at Harvard University graduating summa cum laude in 1897. From 1899-1905 Weatherby was ill and lived with his mother in East Hartford. It was during this time he began his interest in botany and joined the Connecticut Botanical Society. In 1910 Weatherby went to Europe where he met Una Leonora Foster, an artist with an interest in botany. They married in 1917.
Weatherby later was an assistant curator and eventually the curator of the Gray Herbarium, specializing in the study of wildflowers.
In 1951 a biography of Wetherby by Una was published.[1] There are also tributes in professional journals <reff>M. L. Fernald. "Charles Alfred Weatherby, Botanist and Helper of Botanists." Rhodora 51 (1949).</ref>,[2][3]
