Source-derived summary

Theodore Christopher Marceau (May 28, 1859 – June 22, 1922) was an American photographer. He worked for the United States federal government, photographing the 1882 transit of Venus in Chile, and for the states of Ohio and California, before establishing his own studio in Cincinnati. He relocated to New York City in 1900.

Marceau died of a heart attack in 1922 at his home in Premium Point, New Rochelle, New York. His studio was inherited by his son Theodore Jr., who sold it shortly afterward.

Editorial summary

This brief starts where responsible research should: with the source description of “Theodore C. Marceau” as american photographer (1859-1922). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1859, 1922, 1882, 1900—that can be checked directly. The authority record carries competing date values—1859-05-28, 1858-05-29, 1859-05-29—which should remain separate until their references and qualifiers are resolved. The account is most persuasive where Theodore, Marceau and American can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american photographer (1859-1922). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 24, 2024. The linked authority identifier is Q20880823. VIAF identifies the subject as 83637300. The Library of Congress control number is no2009046107. 3 of 5 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
