Strong described organisms consistent with Histoplasma capsulatum before Darling, although his work was overshadowed by the latter.

Report on the epidemic of pneumonic plague that raged in Manchuria and north China during the winter months of 1910-11, causing the death of nearly 50,000 people. This was the first outbreak of epidemic pneumonic plague in modern times.

Strong was the first professor of tropical medicine at Harvard. The Harvard School of Tropical Medicine was founded in 1913, the year they undertook this expedition.

"The Hamilton Rice Seventh Expedition to Amazonia was undertaken [under the leadership of Richard Pearson Strong] partly for general geographical exploration and partly for medical investigation in a section of the Amazon Valley which comprises the greater portion of the most tropical parts of Brazil. The expedition was equipped with complete laboratory apparatus and had further help in various hospitals and clinics, particularly in Mangos and Para. The report of the work is divided into three sections: Part I describes the climate and inhabitants of the country and gives full details about various tropical diseases; Part II discusses the medical and economic entomology of the region; and the third part summarizes briefly the various medical and biological observations made by George Shattuck on the Branco, the Uraricuera, and the Parima Rivers, and adds three other chapters on general biology. A very large number of full-page illustrations and cuts in the text will be of great value to all scientists. Certain sections, intended primarily for workers not especially interested in entomology, have been written with as few technical terms and details as was possible under the circumstances" (publisher)

"The Harvard Medical African Expedition of 1926-1927 was an eight-man venture sent by Harvard University for the primary purpose of conducting a medical and biological survey of Liberia; the secondary purpose being to then cross Africa from coast to coast - west to east - through the Belgian Congo (and other regions) so as to make a comparative study of their Liberian findings.^[1][2] Furthermore, the Liberian interior was next of kin to being terra incognita in the West, there having been no previous medical or scientific survey of the region, nor any recorded expedition into the Liberian hinterlands.^[1] The Expedition leader was Richard Pearson Strong (Harvard's first Professor of tropical medicine),^[3] with the others being zoologists Harold Jefferson Coolidge Jr. (Assistant Curator of Mammals at Harvard) and Dr. Glover Morrill Allen, entomologist Dr. Joseph Charles Bequaert, botanist and Washington University Professor David H. Linder, bacteriologist Dr. George C. Shattuck, clinician Dr. Max Theiler, and Assistant Ornithologist Loring Whitman (also a Harvard medical student and the Photographer).^[4][1] The Expedition was a success and, while its "chief objective was the investigation of tropical diseases, many zoological specimens were collected and the customs of the native tribes were studied."^[5] The story of their travels back and forth across Liberia, and reports of the diseases found that ailed the inhabitants, animals and plants was published in the two-volume The African Republic of Liberia and the Belgian Congo: Based on the Observations Made and Material Collected during the Harvard African Expedition, 1926-1927 written by Dr. Strong in a partnership with other Expedition members and Harvard officials" (Wikipedia article on Harvard Medical African Expedition (1926-1927) ).

The expedition made 5 silent films. When I checked in May 2020 4 of the 5 were available at Vimeo.com: https://vimeo.com/search?q=harvard+african+expedition

In depth study of onchcerciasis in Guatemala, where "the disease was of real importance to human beings" at the time. Each of the 4 authors contributed a separate part of the report.
