He was a generalist, not in the sense of one who hasn't specialized in anything or who knows a little bit about a lot of things, but in the sense of one who has demonstrated the ability to probe deeply into diverse subjects and to contribute new and illuminating knowledge about them. He was extraordinary also in his leadership capabilities, exercised first as chief of the Branch of Military Geology, which he helped to found in 1943, and then as chief geologist of the U.S.

Caciclice Fly Cases from the Green River Formation of Wyoming," and subsequent papers clealt with its mineralogy, plant and animal fossils, physical structures such as varves and mud cracks, stratigraphy and areal geology, and geochemistry, as well as the climate of the Green River Epoch and the paleolimnology of the Green River lakes.

Not only did he examine the algal ooze microscopically to identify microorganisms and the evidence for their activities, he mobilized experts in the nation to identify various organic compounds and microbes existing in the organic sediment, and to develop tools for sampling the ooze and conducting an situ measurements of geochemical parameters. His main effort was directed to unravelling the secret of how the algal matter resisted decay in a subtropical to tropical environment and how relatively oxygen-rich algal matter changed with time to the hydrocarbon-rich organic matter of oil shale in an ordinary diagenetic environment.

His prediction was correct, the controversy has run its course, and now in the aftermath Bradley's perception and the breadth of his observations have re-emerged. His original stratified lake model, from the standpoint of integrated geochemical, sedimentological, paleogeographic, and paleoecological evidence, is still supported for most of Green River time, and most of the varved oil shale.2 Although the Green River Formation was the stimulus for much of Bill's work, his fielct studies inclucled geologic map2 Erle Kauffman 1979: personal communication.

Through his membership, Bill contributed to the activities of a diverse array of organizations: National Academy of Sciences, American Philosophical Society, American Acaclemy of Arts and Sciences, Geological Society of America, American Society of Limnology and Oceanography, International Limnological Association, American Association for the Advancement of Science, American Association of Petroleum Geologists, Botanical Society of America, Sigma Xi, Society of Economic Paleontologists and Mineralogists, Geological Society of Washington, and the Cosmos Club of Washington. Several of these organizations honoree!

His life was a joyous and satisfying one to him and an enriching one for his family, his friends, his scientific organizations, his country and its Geological Survey, and his science. He cried of a stroke on April I2, 1979, eight days after his eightieth birthday.
