Who was Edwin Hubble's wife?

Edwin Hubble’s wife was Grace Burke, more fully known as Grace Lillian Burke Leib Hubble.

Hubble married Grace on February 26, 1924. She was the daughter of John Patrick Burke and Luella Kepford Burke. Before marrying Hubble, she had been married to geologist Earl Leib, who died in an accident in 1921; biographical sources therefore sometimes include “Leib” in her full name.

Grace remained a private figure while Hubble became one of the twentieth century’s best-known astronomers. She supported him through his demanding observing career at Mount Wilson Observatory and cared for him after he suffered a heart attack in 1949.

After Hubble’s death in 1953, Grace guarded his privacy, including the location of his burial. She also donated much of his correspondence, photographs, notebooks, and observing records to the Huntington Library after her death in 1980. The other choices are famous women astronomers, but none was Hubble’s wife.
