Dr. Richard Stegemeier, former chairman and
chief executive officer of Unocal Corp., will deliver a public lecture on
global warming, “Global Warming – Physical or Political Science?”, at 10 a.m.
Friday, April 4, in the Missouri Room of the Havener Center on the Missouri
University of Science and Technology
campus.         

Stegemeier earned a mining engineering degree
at Missouri S&T in 1950. During his 45-year career with Unocal, Stegemeier
worked in the United States, Japan, Australia, Borneo, Sumatra, Bangladesh,
Burma, India, Pakistan and the
Philippines.         

When he became president and CEO of Unocal in
1985, the price of oil had dropped from $29 per barrel to $12 per barrel, and
the corporation was fighting off a hostile takeover from tycoon T. Boone
Pickens.         

Under Stegemeier, the corporation survived and
thrived, becoming the ninth largest oil company in the U.S. Unocal eventually
merged with Chevron Corp. in
2005.         

Stegemeier is on the board of directors of 11
U.S. companies. In 1992, he was elected to the National Academy of Engineering
and in 1998 he was awarded the American Petroleum Institute’s Gold Medal for
Distinguished Achievement.
