Parker D. Trask

Parker D. Trask was a visiting geologist at Scripps Institution of Oceanography. From 1926 to 1931 he was a research associate with the American Petroleum Institute (API), working on studies related to petroleum source rocks. In 1931 the source-bed project became a joint undertaking with the API and the U.S. Geological Survey (USGS), and Trask became a USGS employee, a connection he retained full time for 15 years and part time thereafter until his death in 1961.
