Biographical Note

Edwin Powell Hubble, an observational astronomer, was born November 20, 1889, in Marshfield Missouri. He attended the University of Chicago (1906-1910), where he studied physics and astronomy, and at Queen's College, Oxford University, where, as a Rhodes Scholar, he received a B.A. in Jurisprudence in 1912. After a year as a high school teacher in New Albany, Indiana, Hubble returned to the University of Chicago in 1914 to do graduate work in astronomy under Edwin Brant Frost at the Yerkes Observatory. Completing his Ph.D. in 1917, Hubble immediately joined the U.S. Army, serving as an officer in the infantry from 1917 to 1919. In 1919, Hubble joined the staff of the Mount Wilson Observatory, a position he held until his death on September 28, 1953. Hubble married Grace Burke, a graduate of Stanford University, on February 26, 1924.
Although Hubble's earliest astronomical observations concerned galactic nebulae, from 1922 on Hubble began to use the 100-inch reflector at the Mount Wilson Observatory to view what are now called galaxies (Hubble used the term "extragalactic nebulae"). In 1924, Hubble published "Cepheids in Spiral Nebulae," which contained the first observational evidence that the nebulae were beyond our own stellar system. In 1926, Hubble presented a system for the classification of galaxies (elliptical, spiral, barred spiral, or irregular). The classification system still in use is based upon the scheme proposed by Hubble. By the late 1920s Hubble began to focus his attention on the determination of an extragalactic distance scale. Combining twenty-four distances he had calculated with the corresponding redshifts, Hubble discovered a linear relation between the distance of distant galaxies and their speeds of recession from us. This relation, known as Hubble's Law, provided the first observational evidence of the expansion of the universe and supported what others had predicted on the basis of Einstein's theory of general relativity. In the 1930s, Hubble studied the distribution of galaxies in the sky and discovered that their distribution was uniform, a conclusion which supported the argument that galaxies are the framework of the universe.
Hubble's astronomical career was interrupted by World War II. From 1942 to 1946 he served as Chief of Ballistics and Director of the Supersonic Wind Tunnels Laboratory at the Ballistics Resarch Laboratories, Aberdeen Proving Ground, Maryland. For this service, Hubble was awarded the Medal of Merit.
After the war, Hubble returned to the Mount Wilson Observatory where he became Chairman of the Mount Wilson and Palomar Observatories Research Committee. Hubble spent much of his time on plans for the use of the 200-inch Hale Telescope, which he was the first to use.
In addition to his observational astronomy, Hubble pursued other interests. An avid student of the history of science and philosophy as well as an ardent Anglophile, Hubble was elected Trustee of the Henry E. Huntington Library and Art Gallery upon the death of George Ellery Hale in 1938. In the 1930s, Hubble recognized the inevitability of war with Germany and in the months before the U.S. entered the war he used his notoriety and powers as a public speaker to urge U.S. participation on the side of the United Kingdom. Also an ardent and skilled dry fly fisherman, Hubble spent many vacations in the Rocky Mountains and on the banks of the River Test in England.

Collection Contents

 

Manuscripts

Arranged alphabetically by author, the manuscripts consist primarily of Edwin Hubble's writings. The majority of Hubble's own manuscripts deal with scientific subjects. They include some unpublished articles about Adriaan van Maanen's work and papers discussing the history, philosophy, and nature of science. Also among the Hubble manuscripts are many of his public lectures on such topics as astronomy, smog, war preparedness, and fly-fishing.
Grace Hubble was a faithful chronicler of Hubble's life during their marriage and after his death. In diaries and journals, she described daily happenings at home in San Marino, Calif., and vacations in Colorado, Arizona, the East Coast, Great Britain, and Europe. These diaries discuss the Hubbles' activities, friends, acquaintances, and people they met on their travels. After Hubble's death, Mrs. Hubble prepared rough biographical memoirs of her husband. Divided into topical chapters, the notes and short essays include transcripts of some early Hubble correspondence which is not available elsewhere in the collection. These journals and memoirs supplement the more public record of Hubble's life provided by his own papers.
Also included with the manuscripts are several articles and poems about Hubble, written by family, friends, and colleagues: Helen Hubble Lane, Susan Ertz, Aldous Leonard Huxley, Anita Loos, Milton Humason, Nicholas Ulrich Mayall, and Edward John Moreton Plunkett, 18th Baron Dunsany.

Correspondence

Scope and Content Note

It appears that Hubble was hardly obsessed with saving his correspondence. Only a few letters from the 1920s and 30s survive, but many of these are scientifically important. Included in this group are letters to and from Harlow Shapley, Vesto Melvin Slipher, Willem de Sitter, Henry Norris Russell, Arthur Stanley Eddington, Joel Stebbins, and Otto Struve. There is also an important run of correspondence with Nicholas Ulrich Mayall dating from the early 1930s, regarding the surveys of galaxies made by the two men. Many of Hubble's later letters are carbon copies made from the files of the Mount Wilson Observatory; these letters date from the mid-1940s and are mainly routine. Hubble's only extant personal correspondence was addressed to his wife during 1942 and 1943 when Hubble worked at the Aberdeen Proving Grounds in Maryland and Mrs. Hubble was still in California. The spotty nature of Hubble's own correspondence was explained by Mrs. Hubble: "He had a reticence that demanded privacy from the public."
Most of the personal correspondence in the collection is addressed to Grace Hubble, although a few letters are addressed to her husband. The Hubbles' social circle included a number of persons with whom Edwin Hubble was not professionally associated. Many of these individuals were English --some Edwin Hubble met at Oxford and some the Hubbles met in Hollywood in the 1930s. Friends and acquaintances with whom there is significant correspondence include the Robert Gore-Brownes, Sir Charles Richard Fairey, Henry Herbert Gordon Clark, Philip Henry Kerr (Lord Lothian), Sir Hugh Walpole, Aldous and Maria (Nys) Huxley, Harold Marsh and Fryniwyd Tennyson Jesse Harwood, Frieda (von Richtofen) Lawrence, George Arliss, and Anita Loos.
The correspondence is arranged alphabetically by author and addressee. Letters from one individual to another are ordered chronologically. Within the correspondence are scientific, routine business, and some personal letters written by and addressed to Edwin Hubble, letters to Grace Hubble primarily from literary and show business personalities the Hubbles knew socially, and letters of condolence upon the death of Hubble.
Persons represented by five or more pieces or significant items listed.

Astronomical Working Papers 1925-1929

Scope and Content Note

This section contains almost complete documentation for Hubble's three papers on cepheids (Messier 31, Messier 33, and N.G.C. 6822) published from 1925 to 1929, for his 1930 paper, "The Distribution of Luminosity in Elliptical Nebulae," and for his 1934 paper on the distribution of galaxies in space. Much of the data Hubble compiled in checking Adriaan van Maanen's conclusions concerning the angular rotations of spiral nebulae is also here. There are a few finding charts for clusters of galaxies which were utilized in Hubble's calculation of the velocity-distance relation among extragalactic nebulae. In addition, several star charts and other telescopic photographs have been preserved. The astronomical working papers were organized with the assistance of Dr. Allan Sandage, a former colleague of Hubble's and astronomer at the Carnegie Observatories. The papers have been arranged chronologically according to the particular scientific paper produced from them. The data for each paper is randomly ordered, but the verso of each piece has been numbered in pencil.
