Dr.
Lawrence W. Stark, a professor emeritus of physiological optics
and engineering at the University of California, Berkeley, recognized
worldwide as a pioneer in the use of control and information theory
to characterize neurological systems, died Friday, Oct. 22.
Stark died of cancer at his home in Berkeley at the age of 78,
four years after being diagnosed with Non-Hodgkins lymphoma.
Starks death is a huge loss for the world of optometry,
said Dennis Levi, dean of UC Berkeleys School of Optometry.
His landmark studies on eye movement control truly advanced
the field of vision science.
A neurologist by training, Stark is credited for seminal research
that applied engineering principles, particularly control theory,
to biological systems.
Stark was unique in his ability to identify aspects of engineering
analysis relevant to medicine and biology, said Laurence
Young, Apollo Program professor of astronautics at the Massachusetts
Institute of Technology and Starks first graduate student
at MIT. A perfect example is the seminal work he conducted
in analyzing the way a pupil reacts to light in terms of a linear
control system.
Young pointed out that those same principles have been applied
to such areas as pilot control of airplanes and spacecraft. Characterizing
how the eye moves and how the brain processes visual cues is essential
to understanding how pilots control airplanes, and why people
get motion sickness, he said.
In addition to analyzing the feedback control system governing
pupil contractions, Stark also developed the scan path theory
of eye movements. He studied the way peoples brains viewed
the world and analyzed the vast number of jumping eye movements,
or saccades, people make. He noticed specific sequences
to how people glimpsed a room, face or other scene before them,
and realized how those sequences provided clues to the importance
of pictures generated by the brain.
Starks drive to understand visual processes within an engineering
discipline led to his later research interests in robotic vision
and virtual reality.
Although he was trained in medicine, he was very interested
in the physical sciences and engineering, said Gerald Westheimer,
UC Berkeley professor of neurobiology. He was a true crossover
scientist, bringing applied engineering concepts to neurological
functions, and the variables inherent in biology to engineering.
Stark was born in New York on Feb. 21, 1926. He credited his early
interest in engineering to the influence of his father, an MIT-educated
chemical engineer. He once recalled in an interview how, as a
young boy, he took apart his mothers typewriter and put
it back together again minus four screws. His mother was
impressed with his success, he said, until the typewriter stopped
working a few weeks later.
Undaunted, Stark maintained his curiosity for how things work,
going on to Columbia University and majoring in English, biology
and zoology. After receiving his bachelors degree in 1945,
he joined the military, taking the U.S. Navy up on its offer to
pay for his medical school tuition. Stark went to New Yorks
Albany Medical College, where he earned his M.D. in 1948.
He then spent two years in England at Oxford University and University
College, conducting research in neurophysiology, biochemistry
and biophysics, before returning to the U.S. Navy to serve as
a doctor during the Korean War.
In 1954, after the war ended, Stark joined Yale University as
an assistant professor of medicine.
In 1960, he became head of the neurology section of MITs
Center for Communication Sciences, and in 1965, he founded and
became chairman of the Biomedical Engineering Department, one
of the countrys first bioengineering departments, at the
University of Illinois at Chicago.
He was really one of the first people ever to use engineering
theory to study a physiological system, said Blake Hannaford,
director of the Biorobotics Laboratory at the University of Washington
and one of Starks former Ph.D. students. He played
a pivotal role in the 1950s and 1960s in founding the field of
bioengineering.
Stark joined the UC Berkeley faculty in 1968 with joint appointments
as professor at the School of Optometry, the Department of Electrical
Engineering and Computer Sciences and the Department of Mechanical
Engineering. He also collaborated on neuro-ophthalmology research
with colleagues at UC San Francisco.
He retired from UC Berkeley in 1994, but remained active in his
lab on campus.
He was always questioning, bringing up new ideas,
said Elwin Marg, UC Berkeley professor emeritus of vision science
and optometry and a close colleague of Starks for nearly
50 years. His enthusiasm and curiosity were an inspiration
to his students.
So many of his students went on to distinguish themselves in academic
careers that a scientific conference was held in his honor. In
1994, John Semmlow, a professor of bioengineering at Rutgers University
in New Jersey and one of Starks former students, organized
the First International Conference on Vision and Movement in Man
and Machine, a two-day symposium attended primarily by Starks
colleagues and former students and affectionately nicknamed Starkfest.
Although research papers were presented at the conference and
later published in peer-reviewed journals, including special issues
of the Annals of Biomedical Engineering and Optometry and Vision
Science, participants viewed the event as a chance to honor their
former advisor and renew old friendships, said Semmlow.
Stark maintained a strong bond with nearly all of his students,
said Semmlow, one of two students from the University of Illinois
who followed Stark to UC Berkeley. He had an extremely dynamic
personality. He was also extraordinarily intelligent, very well
read, and he cast his interests in many different directions.
Two more Starkfest meetings have been held since 1994, most recently
in Marseilles, France, in 2002.
Stark received numerous honors throughout his career, including
an honorary Sc.D. from the State University of New York and an
honorary Ph.D. from Tokushima University in Japan. He was named
a Guggenheim Fellow in 1968, a fellow of the Institute of Electrical
and Electronics Engineers in 1970, a recipient of the William
J. Morlock Award in Biomedical Engineering in 1977, and a fellow
of the American Institute of Medical and Biological Engineering
in 1992.
Stark is survived by his partner of 18 years, Jill Strohn of Berkeley,
Calif.; three daughters, Stefanie Stark of Kensington, Calif.,
Nanou Matteson of Berkeley, Calif., and Elizabeth Stark of San
Francisco; Elizabeths mother, Wendy Bartlett of Berkeley,
Calif.; ex-wife, Jeanne Stark-Iochmans of Berkeley, Calif.; his
brother, Matthew of Minneapolis, Minn.; and four grandchildren.
Starks first wife and Stefanies mother, Jane Stark,
died in 2001.
Memorial services at the UC Berkeley Faculty Club are being planned.
When the exact date and time are available, they will be posted
online at http://scan.berkeley.edu/larry.
In lieu of flowers, donations in Starks memory can be made
to the Golden Gate National Parks Conservancy, Fund in Memory
of Lawrence W. Stark, Attn: Audrey Yee, Fort Mason Building 201,
San Francisco, CA 94123-0022. In accordance with Starks
wishes, the money will be used to purchase land that will be kept
preserved and open to the public.
