Source-derived summary

Charles Robert Cross (March 29, 1848 – November 16, 1921) was an American physicist and chair of the physics department at the Massachusetts Institute of Technology from 1877 to 1917.

Biography

Cross was born March 29, 1848, in Troy, New York to George Cross and Lucy Ann Brown. When he was 14, his family moved to Newburyport, Massachusetts where he attended the Putnam Free School, graduating in 1865. He entered the Massachusetts Institute of Technology as a sophomore in 1867 and graduated in 1870 with a Bachelor of Science. Following graduation, he became instructor in physics, assistant professor in 1871, and full professor in 1875. Cross became chair of the MIT physics department in 1877, after the resignation of Edward Pickering.

In 1882, Cross developed and taught the first course in electrical engineering in the country. He instructed on telegraphy, telephony, and dynamo electric machinery. He taught this course until 1902, when he established the Department of Electrical Engineering. In 1900, Cross established a course in electrochemistry, the first in the United States.

Editorial summary

Begin with the source’s own compact description: “Charles R. Cross (physicist)” is american physicist (1848-1921). The dossier treats that line as a proposition to test through Charles, Cross and physicist, not as a finished interpretation.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1848, 1921, 1877, 1917—that can be checked directly. The authority record carries competing date values—1848, 1848-03-29—which should remain separate until their references and qualifiers are resolved. For this dossier, Charles, Cross and physicist is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “american physicist (1848-1921)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

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 Apr 24, 2026.

The Library of Congress control number is no2011086835. 4 of 4 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 1848, 1921, 1877 and 1917.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.

How to read it
