John William Hotson

[4] In 1910, after a year of teaching botany at Pomona College,[4][5] he quit his position with the intention to attend Harvard University for doctoral studies.

[10] Hotson organized the "first fungus herbarium at Washington and many of his specimens are cited in treatments of Agaricus, Amanita, and other genera of agarics.

[12] Hotson acted as supervisor of graduate students during his tenure, including University of Washington president, Dr. Henry Schmitz (1952–1958).

"[15] Long recognized for its absorbency, Sphagnum moss has been employed as a diaper material, as a feminine hygiene product, and for bandages.

Davis and Banack (2012) recorded that among the Kiluhikturmiut Inuinnait of Nunavut, Canada, Sphagnum was used for menstrual pads, diapers, and bandages.

On Nunivak Island, Alaska, the Nunivaarmiut (Yup'ik) made diapers by placing dried Sphagnum in a scraped and softened seal skin.

In the United States, 500,000 dressings were prepared after the American Red Cross approval of sphagnum in March, 1918, until the war's end in November.

"[1] Hotson served on several professional associations, including as a director on the board of the American Phytopathological Society, Western Division (1936).

[24] In 1962, faculty, alumni, and friends of Hotson, Rigg, and Frye established the Frye-Hotson-Rigg Award to honour the former professors of Botany at the University of Washington.

The award is given to undergraduate Biology students "conducting research using a plant, algae, or fungi system for work in botany, ecology, evolution, taxonomy, environmental science, or biodiversity.
