Allen W. Hatheway (M.S. ’66, Ph.D. ’71; Geological Engineering) was named by Gerard Kuiper as an LPL Research Associate to perform the terrestrial technical proof of Professor Robert Strom’s correct conclusion that the lunar dimple craters were, in reality, collapse depressions on basaltic lava fields. (As an unrelated yet interesting coincidence, Mrs. Kuiper had a first cousin, Sanford Dudley, who was Best Man at the 1930 marriage of Allen’s parents.)

Hatheway’s dissertation, Lava Tubes and Collapse Depressions, led to a long career in applied engineering followed by nineteen years as a professsor of Engineering at the University of Missouri.

In 1988, Allen began specializing in environmental remediation of former manufactured gas plants (1792-1990) and other coal-tar plants. Allen’s second gasworks technical monograph, co-authored by Tom B. Speight, was published in January 2018.
