| biography:
| Astronomer, born in Zürich, N Switzerland. He studied at Zürich and Göttingen universities, moved to America in 1915, then worked at the Lick Observatory, CA (1918–38) and the astronomical department of the University of California, Berkeley (1938–51). In 1922, by observing a solar eclipse, he was able to confirm Einstein's theory of relativity. He made extensive studies of star clusters and galaxies, and found an interstellar haze absorbing light from distant stars, which had an important effect on ideas about the scale of the universe. |
