Edwin P. Hubble: The man behind the name When talking about the Hubble Space Telescope one man is often forgotten: That man who gave the space telescope its name: Edwin Powell Hubble. Today, most astronomers see him as the most important observational cosmologist in the 20th century and he played a crucial role in establishing the field of extragalactic astronomy. As a result of Hubble’s work, our perception of mankind’s place in the Universe has changed f orever: humans have once again been set aside from the centre of the Universe. When scientists decided to name the Space Telescope after the founder of modern cosmology the choice could not have been more appropriate. of Spanish and Physics, who has been a loyal friend to us in our senior year, ever willing to cheer and help us both in school and on the field, we, the class of 1914, lovingly dedicate this book.” When the school term ended in May 1914, Hubble decided to pursue his first passion and so returned to university as a graduate student to study more astronomy. War postpones Hubble’s astronomical debut Early in 1917, while still finishing the work for his doctorate, Hubble was invited by George Ellery Hale, founder of the Mount Wilson Observatory, in Pasadena, California, to join the staff there.
