Source-derived summary

Jesse William Lazear (May 2, 1866 – September 25, 1900) was an American physician. In 1900, he deliberately allowed a mosquito to bite him to test the hypothesis that mosquitoes were the vector for yellow fever transmission. He contracted the disease but did not recover and died on September 25, 1900.

Background

Lazear was the son of William and Charlotte née Pettigrew. He attended Trinity Hall Military Academy and Washington & Jefferson College, both in Washington, Pennsylvania, and obtained his Bachelor of Arts in 1889 from Johns Hopkins University and his M.D. in 1892 from the Columbia University College of Physicians and Surgeons. He did his specialization in Paris at the Institut Pasteur. In 1896 he married Mabel Houston with whom he had two children. He was also a member of the Phi Kappa Psi fraternity.

Career

Lazear was a physician at the Johns Hopkins Hospital in Baltimore starting in 1895, where he studied malaria and yellow fever. In 1900 he reported for duty as the assistant surgeon at Columbia Barracks (Quemados, Cuba) for the United States Army.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american physician (1866-1900). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q2471960. VIAF identifies the subject as 19356718. The Library of Congress control number is no2002108793. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1866, 1900, 1889 and 1892.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
