Devotion is one characteristic in Hubble that allowed him to do his work so well. Whether it was devotion to his family or to his work. It started when he was just a youth; he was in a family of seven children and was expected to earn money for the family (Whitney 222).Hubble’s devotion was mental and also physical. Hubble worked at Mount Wilson for most of his career. Here, “he spent hundreds of bone-numbing hours in the observer’s cage at Mount Wilson telescope. Anyone who has spent time in ‘the cage’ knows what an extraordinary effort of will it can demand: total concentration, and an ability to suppress shivers in the constant chill, lest you vibrate the telescope.” (Smoot 42).Hubble’s hard work and long hours were recognized by his fellow astronomers. The author of Wrinkles in Time, George Smoot, said, “Night after night Hubble photographed the nebulae, devoting himself to his goal so completely that he was perceived as arrogant and elitist” (44).Unable to complete his any tasks on his own, Hubble hired an assistant. He hired Sandage. Sandage would work with Hubble and learn techniques that Hubble used to hopefully do research of his own in the future. Hubble taught Sandage how to classify galaxies so he could continue Hubble’s work. As Hubble age, he was unable to use the telescope any more. He didn’t have the strength or energy to stay in the cage for long periods of time. So, he sent Sandage to carry out tasks for him. Everyday Sandage would be given coordinates or jobs by Hubble. When Sandage was done recording he data of his work, he would go back to Hubble and give him the results (Overbye 22). This shows how devoted he was to his research, even if he was unable to handle the job due to old age he compromised. All of Hubble’s work and Sandage work was done on the 100-in telescope, yet Hubble was still able to find the Andromeda Nebulae...
