George Demas
George Demas (April 28, 1958 - December 23, 1999) was an American pedologist whose pioneering studies of subaqueous soil contributed to the understanding of soil formation and the expansion of the concept of soil. USDA soil taxonomy was revised as a result.
Born in the U.S., he earned a B.S. in Soil Science from the University of Maryland, College Park in 1980 followed by an M.S. in soil genesis in 1982. He earned a Ph.D. from the University of Maryland in 1998. His thesis on subaqueous soils earned two awards USDA - Secretary’s Honor Award for Scientific Research, and Soil Science Society of America (SSSA) - The Emil Truog Award〔()〕 for outstanding contribution to Soil Science.
George Demas worked as a soil surveyor for the Natural Resources Conservation Service in the states of Maryland and New Jersey from 1982 to 1994. During this time he determined that submerged sediments function in the landscape sufficiently similar to soils to be indistinguishable. Soil Survey Horizons published his concept in 1993. He returned to the University of Maryland and researched his ideas from 1994 to 1998. He resumed his duties with USDA-NRCS and continued working until his death in 1999 after contracting pneumonia.
