Schumacher (March 14, 1892 – June 3, 1967) was a prominent forest biometrician. He served on the forestry faculty at The University of California before being called to work as chief of the section forest measurements, U.S. Forest Service.[2] His interest in statistics led him to an affiliation with R.A. Fisher, and Schumacher led early advances to adopt statistical methods in forest inventories and silvicultural research.[3] He joined the faculty of the Duke Graduate School of Forestry as one of its original seven faculty members.[4] He co-authored textbooks on forest mensuration and sampling with other notable forest biometricians Donald Bruce[5] and Roy A. Chapman.[6] He was the first to apply the equation form Y = ea+b/X, widely known as the Schumacher equation, to timber growth and yield modeling.[7] In 1957 he was elected as a Fellow of the American Statistical Association.[8] Schumacher was named a Fellow, Society of American Foresters in 1959[9] and was awarded an honorary doctorate from North Carolina State University the same year.[10] References1. ^Schumacher, F.X. 1939.
