Source-derived summary

William Emlen Roosevelt (April 30, 1857 – May 15, 1930) was a prominent New York City banker who held a wide range of positions in numerous organizations and was a cousin of United States President Theodore Roosevelt. He was president of Roosevelt & Son, the banking firm founded by his father James Alfred Roosevelt.

Early life

William Emlen Roosevelt was born to James Alfred Roosevelt and Elizabeth Norris Emlen. His maternal grandparents were William Fishbourne Emlen (1786–1866) and Mary Parker Norris (1791–1872) and his paternal grandparents were Cornelius Van Schaack Roosevelt (1794–1871) and Margaret Barnhill (1799–1861).

Career

He was director of the Chemical Bank of New York, the Gallatin National Bank, and the Astor National Bank, and later sat on the boards of the Grand Hanover and the Bank of New York. He was president of Roosevelt Hospital, founded by his distant cousin James H. Roosevelt. He was an officer of the National Guard for 16 years, major and quartermaster of the First Brigade. Roosevelt became involved in telecommunications companies, formed the Mexican Telegraph Company and Central and South American Telegraph Company, and was eventually director of the International Telephone and Telegraph Company.

Theodore Roosevelt and he had a very close relationship as cousins. Emlen was not interested in politics other than to support his cousin's bids for public office, and Theodore, busy with conservation advocacy, had little time to attend to financial matters.

For this dossier, Emlen, Roosevelt and York is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “new York City banker (1857–1930)” 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

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated May 24, 2026. The linked authority identifier is Q5372659. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1857, 1930, 1786 and 1866.

Critical limits

Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
