Dr. Lloyd Stover, an engineer, scientist and attorney, whose wide ranging interests touched on astronautics, oceanography, global warming and the environmental impacts of technological development, often in advance of his peers, died on Jan. 27 in Tallahassee, Florida at age 91.

Dr. Stover survived World War II as a navy carrier pilot, including the Battle of Midway. He obtained engineering and law degrees under the GI Bill and subsequently a PhD in oceanography. After a brief law practice in Washington, D.C., he became range operations manager at Cape Canaveral in the early days of the space program, then served as director of flight test for the Atlas, and site activation manager (Titan ICBM program). Afterward, he tested the Distant Early Warning System (Alaska through Canada) and installed a Tropospheric Scatter Communications System for NATO that extended from Norway to Turkey.

Dr. Stover was a senior research scientist at the Institute of Ocean and Atmospheric Sciences of the University of Miami and served as a visiting professor at Florida Atlantic University, University of Arizona, University of Izmir (Turkey), and University of Tehran (Iran).

Dr. Stover served as president of Ocean Marine Products which contributed to the Navy's Man in the Sea Program and worked on a manned Undersea habitat with Jacques Cousteau. He was chief scientist for Environment and Technology Assessment Inc., which provided consultant services to the UN and World Bank on energy and environmental issues in Yugoslavia, Turkey, Iran, Saudi Arabia, Venezuela and the Philippines.

Dr. Stover served as a science adviser to senators Holland of Florida, Jackson of Washington, Muskie of Maine and Vice President Humphrey. He was honored by the American Association for the Advancement of Sciences for his early work in warning of the potential consequences of global warming. He served as science adviser to the presidential transition teams of Carter and Clinton.

For many years he taught Elderhostel programs in Maine and Florida and he has written articles on science and public policy. He also wrote a book, Twentieth Century Odyssey, an examination of the main ideas and events of the century, and his involvement with them. He thanks his daughter, Jil, for her invaluable help in seeing it printed.

He is survived by his daughters, Kim Spencer and her husband Troy, Nan Worsowicz and her husband Tim, and Jil Weisner and her husband Eric; six grandchildren, Katie Worsowicz, Kevin Worsowicz, Coleman Spencer, Kayla Spencer, Cameron Weisner and Daniel Weisner.
