Source-derived summary

John Sealy Livermore (April 16, 1918 – February 7, 2013) was an American geologist who discovered or helped to discover four major gold deposits in northern Nevada.

Livermore was born in San Francisco, California, and was descended from a pioneer California family with roots in Maine.

An ancestor, Elijah Livermore, built a grist mill and a saw mill on the Androscoggin River in 1791. The town of Livermore Falls, Maine, is named after him.

His great-grandfather, Horatio Gates Livermore, came to California from Maine during the Gold Rush in 1850, and later became a California State Senator from Eldorado County. His great-grandfather and his grandfather, Horatio Putnam Livermore, who came to California in 1856, used their Maine mill experience to become involved in the earliest days of hydroelectric power, helping to build the original Folsom Dam. His father, Norman Banks Livermore was a founding board member of Pacific Gas and Electric. His mother, Caroline Sealy Livermore, was a conservationist in the San Francisco Bay Area, working on protection of the Marin Headlands and Richardson Bay. Mount Livermore on Angel Island is named after her. He had four brothers, environmentalist and timber executive Norman Livermore (1911-2006), Putnam Livermore, Robert Livermore and George Livermore.

Editorial analysis

Why this record matters

“John Livermore” is worth following because a concise public description often conceals a longer documentary argument. Here, John, Livermore and American provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 31, 2026. The linked authority identifier is Q6245002. VIAF identifies the subject as 310520933. The Library of Congress control number is no2014083469. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1918, 2013, 1791 and 1850.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
