Ivy Kellerman Reed (Oshkosh [Wisconsin], July 8, 1877 - La Jolla [California], February 7, 1968) was an American author in the international language Esperanto. An accomplished linguist with four academic degrees for work in Latin, Greek, Sanskrit, and Persian and half a dozen modern languages, Reed was an ardent Esperantist. Her Practical Grammar of the International Language, first published in 1915, ran to several editions, and is available today online from Project Gutenberg free of charge. She was the translator with Ralph A. Lewin, of the famous Esperanto edition of Winnie-the-Pooh. She also translated Shakespeare's As You Like It, the first performance of which was given at the sixth World Esperanto Congress in Washington DC in 1910.
