content: A metal tag on this device reads “WILLSON / THERMO-ANEMOMETER / MANUFACTURED BY / WILLSON PRODUCTS, INC. / READING, PA., U.S.A. / PAT. APPLD. FOR.” A label explains in part, “The heated bulb cools off when exposed to air currents, and the extent of cooling as indicated by the difference in temperature between the heated and unheated thermometers varies with air velocity.” The form was developed in the late 1930s by Constance Yaglou (1897-1960), a native of Turkey who spent his career teaching at the Harvard University School of Public Health.
