Biography

[edit]

In 1906, his parents took him to Italy for two years, then to Indiana, where they lived until 1913, when they moved to California.[1]

As a child, he showed a great interest in mechanical design and drawing. He was hired as a draughtsman for the design of the Mount Wilson Observatory's 100-inch (2.5-metre) Hooker telescope.[1]

He received his bachelor's degree from the California Institute of Technology (Caltech) in 1921, and in 1924, he obtained his Ph.D. for his work with John August Anderson on the exploding wire method, to obtain laboratory spectra at high excitation and ionization energies.[2]

He then spent a year at the Cavendish Laboratory at Cambridge University, and worked at the physics laboratory of the Mount Wilson Observatory for the rest of his life.[1][2]

He died prematurely of cancer at the age of 39.[1]
