Photograph of Adolfo Lutz by an unidentified studio photographer, as printed in L. O. Howard, 'Some pioneers in mosquito sanitation and other mosquito work, II', The Popular Science Monthly 87 (December 1915), p. 170; scan via the Internet Archive and Wikimedia Commons (public domain). Downscaled. · Halftone photographic portrait of Dr. A. Lutz, printed with the caption 'Dr. A. Lutz, chef de service, Oswaldo Cruz Institute, Rio Janeiro, Brazil, formerly director of the Bacteriological Institute, Sao Paulo' in L. O. Howard's article in The Popular Science Monthly, volume 87, December 1915, plate p. 170 (credited on the plates to the U.S. Department of Agriculture). The studio photographer's signature at the lower right is illegible. The file is the Commons-extracted plate (1197 x 1533 pixels, original size) downscaled to 937 x 1200 with no upscaling. · Public domain in the United States: published in New York in 1915 (before 1931). The Internet Archive item for the volume carries no copyright-status statement and the Wikimedia Commons file page carries a United States public-domain tag with the Internet Archive volume as its source; the underlying studio photographer is unidentified, so the basis is the 1915 US publication date, not a holder licence.
Trait Constellation
Key Achievements
Led the Bacteriological Institute of Sao Paulo from 1893 to 1908 (now the Instituto Adolfo Lutz), where he identified local cholera and plague outbreaks and the typhoid nature of the 'Sao Paulo fevers'.
In 1902-03 repeated the mosquito yellow-fever transmission experiments in Sao Paulo and, with Emilio Ribas, planned a prophylaxis programme against the vector.
Published the 1908 case report of what is now called paracoccidioidomycosis, and studied helminths including the snail hosts of the schistosome and Brazilian mosquitoes.
Moments That Reveal Them
For the December 1902 yellow-fever trials he bred mosquitoes from larvae, infected them from a mild case, kept them over 12 days and used six adult volunteers.
Consistent with a careful, controlled approach to experimental design. Experimentation
He kept defending the mosquito-transmission theory of leprosy until his death in 1940; a contemporary critic said he still offered no documentation after forty years.
Consistent with long persistence in a hypothesis that outlasted its supporting evidence. Persistence
Turning Points
In 1908 he left the Bacteriological Institute for the Oswaldo Cruz Institute in Rio, where a historian says he could return to zoology and solitary laboratory and field work.
Consistent with a preference for solitary research over public-health leadership, as one historian reads it. Leadership Drive

CANONICAL SIGNIFICANCE SOURCE: after Swiss medical studies and European laboratories he practised in Limeira, worked with Unna in Hamburg, studied leprosy in Hawaii, headed the Bacteriological Institute of Sao Paulo (now the Instituto Adolfo Lutz) from 1893 to 1908 and then worked at the Oswaldo Cruz Institute until 1940; almost two hundred papers on a wide range of subjects, about a quarter on helminths including snail hosts of the schistosome; in microbiology he first identified cholera and plague outbreaks locally and the typhoid nature of the 'Sao Paulo fevers'; with Splendore studied sporotrichosis (1907) and made fundamental contributions to South American blastomycosis; in 1902, on hearing of Reed's yellow-fever results, repeated the transmission experiments in Sao Paulo, being bitten with others by infected Aedes aegypti, and planned a prophylaxis programme with Emilio Ribas; in 1903 said Aedes aegypti was not the only yellow-fever vector; anopheline breeders in bromeliads; Culicidae and other fly families, scorpions, snakes and frogs.

Born in Rio de Janeiro in 1855 and educated in Switzerland; clinic in Limeira; Hamburg research with Unna on leprosy bacteriology; leprosarium in Hawaii 1889-1892; director of the Bacteriological Institute of Sao Paulo from 1893 where he 'played a decisive role' against infectious diseases; Oswaldo Cruz Institute from 1908 until his death; 'tireless researcher' with foundational studies in parasitology, veterinary medicine and microbiology. Brief institutional note, admiring; gives the Swiss diploma year as 1890 where other sources say 1878-1879.
- Jaime Larry Benchimol, 'Adolpho Lutz: um esboco biografico' (Adolpho Lutz: a biographical sketch), Historia, Ciencias, Saude-Manguinhos 10(1), 2003 (SciELO full text, Portuguese, read in the relevant sections: Hawaii, the Bacteriological Institute, the yellow-fever controversy and the final assessment). Scholarly historian's account up to 1908: conflicting versions of why he left Hawaii (a haughty reply to an inquiry commission in one, an incident involving a missionary he disliked in his daughter's); that he and a nurse alone among the doctors did not fear contagion (reported from earlier biographers); that he was 'the soul, the brain and the main work force' of the Bacteriological Institute, which he directed for 15 years, and fought hard controversies with most of the medical field; that his diagnoses rested on laboratory proofs most doctors could not use; the 1902-03 yellow-fever experiments he designed (mosquitoes bred from larvae to exclude contamination, a mild source case, six adult Brazilian volunteers, a longer maturation period to avoid severe infection); his mosquito-collecting network from 1898 and the delayed publication (1903) of his bromeliad-malaria discovery; and the closing judgement that he lacked Oswaldo Cruz's qualities as chief and gatherer of disciples, disliked publicity, left public credit to Emilio Ribas and preferred solitary laboratory and field work, moving to Manguinhos to return to zoology. Independent, critical in places; the leadership judgement is one historian's interpretation.
- Jaime L. Benchimol and Magali Romero Sa, 'Adolpho Lutz and controversies over the transmission of leprosy by mosquitoes', Historia, Ciencias, Saude-Manguinhos 10 (suppl. 1), 2003 (SciELO English full text; the abstract and the sections on the 1915-1922 commissions and congresses, the 1940s and the critics were read; the earliest sections were skimmed). COUNTER-VOICE: from Hawaii on he held that leprosy was transmitted by mosquitoes and sought proof for decades; the research was not successful, yet he kept his conviction until his death in 1940; the Brazilian leprosy commission accepted a mosquito-prophylaxis clause in 1915 but he found less support by 1921-22; the leprologist Belmiro Valverde, quoted at length, called the thesis dogmatic and said that after forty years Lutz still could not give the slightest documentation; later work by Souza Araujo in the 1940s argued that haematophagous insects might transmit leprosy under some conditions. Scholarly, with a quoted contemporary critic.

Dermatology-history article: Lutz's April 1908 article described clinical, histopathological and mycological findings of two oral cases ('mycose pseudococcidica'); he had examined the index patient of Posadas and Wernicke's coccidioidomycosis case in 1897 and so knew the disease; he excluded an epithelial cancer histologically, cultured the agent, described budding and the difference between tissue and culture forms; a founding member of the Brazilian Society of Dermatology. Admiring centenary tribute that relies on his original article.

Institutional history: the Bacteriology Laboratory was headed by Lutz from April 1892 (per this note), took the name Bacteriological Institute in mid-1892 and was officially created on 4 September 1893. Short institutional note; its 1892 start differs from Benchimol's 1893 appointment date, so rows avoid the date.
