Our home was filled with books, and all of us were avid readers. My reading at that time ran toward naval history, which was complemented with realistic scale-models and simulated naval battles using an elaborate mathematical system for rating each warship and the effects of combat on them. During my sophomore year in high school, my math teacher, who also coached tennis and basketball, encouraged me to take up tennis - which led me onto the varsity tennis team for my junior and senior years, and into a full decade of intense athletic competition. As a senior, I played on the varsity basketball team. After graduation from high school in 1943, almost all of my male classmates immediately entered the military services. However, because I was still well under the compulsory draft age of 18, I enrolled at Ohio Wesleyan and attended the university year-round for the next two years. During these war years, only 30 or 40 civilian males were on campus, plus about 200 naval officer trainees and 1,000 women. With so few men available, I played on the University basketball and baseball teams, and wrote much of the sports page for the University newspaper. I then hitchhiked 2000 miles back to Ohio, traveling through Yosemite and Yellowstone Park on the way.

Rowland, F. Sherwood, in full FRANK SHERWOOD ROWLAND (b. June 28, 1927, Delaware, Ohio, U.S.), American chemist who shared the 1995 Nobel Prize for Chemistry with chemists Mario Molina and Paul Crutzen for research on the depletion of the Earth's ozone layer. Working with Molina, Rowland discovered that man-made chlorofluorocarbon (CFC) propellants accelerate the decomposition of the ozonosphere, which protects the Earth from ultraviolet radiation. Their findings eventually brought about international changes in the chemical industry. Rowland was educated in his hometown at Ohio Wesleyan University (B.A., 1948) and at the University of Chicago (M.S., 1951; Ph.D., 1952). He held academic posts at Princeton University (1952-56) and at the University of Kansas (1956-64) before becoming a professor of chemistry at the University of California, Irvine, in 1964. At Irvine in the early 1970s he began working with Molina. Rowland was elected to the National Academy of Sciences in 1978. Rowland and Molina theorized that CFC gases combine with solar radiation and decompose in the stratosphere, releasing atoms of chlorine and chlorine monoxide that are individually able to destroy large numbers of ozone molecules. Their research, first published in

F. Sherwood Rowland In 1995, F. Sherwood (Sherry) Rowland shared the Nobel Prize for chemistry with his associate Mario Molina for their groundbreaking work on CFCs and ozone, which led to the landmark ban of CFCs from aerosol cans. Q: What do you do, and how would you explain it to a small child? A: I'm a professor of atmospheric chemistry. I'd say that I try to determine what controls the gases in the atmosphere. Q: Tell me about yourself. A: I'm sixty-nine years old. My wife's name is Joan, pronounced with two syllables. We were married in 1952 and have two children: Ingrid, a professor of Art History at the University of Chicago; and Jeffrey, an MBA financial analyst who has worked chiefly in aerospace. Q: Any pets? A: Not now. We had cats from the time of our marriage until a few years ago. We had one cat for twenty years that died in 1980. Then our daughter brought another one home from Rome, but that cat died after 8 years. Lately, my wife Joan and I do so much traveling that we're both away from home for several months each year that's a lot of time to be worried about who's taking care of the cat. Q: What was the last environmental book you read?

ROWLAND, F. SHERWOOD rowland@uci.edu Research Professor at the Department of Chemistry, Bren Chair , Earth System Science, University of California , Irvine, United States. Research interests : His research group is currently studying the composition of the earth's atmosphere in (a)remote locations throughout the Pacific region from Alaska to New Zealand:(b)highly polluted cities throughout the world; and (c) areas with special conditions, such as burning forests and/or agricultural wastes, or the marine boundary layer in oceanic locations with high biological emissions. Whole air samples are collected on land, ships, and aircraft and are returned to our laboratory for analysis. Gas chromatography utilizing flame ionization detection, electron capture detection, and mass spectrometry is our main analytical tool. A three gaschromatograph analytical system is used to quantify about 150 halocarbons, nonmethane hydrocarbons, and alkyl nitrates ranging in mole fraction from about 2 parts per billion to 20 parts per quadrillion. In an attempt to determine "background" concentrations of selected trace gases, since 1978 they have been collecting air samples at surface locatins every three months in Pacific regions from northern Alaska to southern New Zealand. Results from this "background" study recently led to our discovery that methyl bromide, a gas that significantly affects stratospheric ozone concentrations, has a tropospheric seasonal cycle. This finding provides an important constraint on hemispheric and seasonal methyl bromide sources and removal processes.

Conference Participants Unveiling The Solar System F. Sherwood Rowland University of California, Irvine Lecture Our Changing Atmosphere October 8, 1997 - 10:00 am - Lund Arena Dr. F. Sherwood Rowland , Donald Bren Research Professor of Chemistry, came to the University of California, Irvine in 1964 as the first chair of the Department of Chemistry. He previously held faculty positions at Princeton University and the University of Kansas. He earned his bachelor's degree from Ohio Wesleyan University and his master's and doctoral degrees from the University of Chicago. He is currently the elected Foreign Secretary of the National Academy of Sciences. Dr. Rowland is a specialist in atmospheric chemistry and radiochemistry, and was, with colleague Mario Molina, the first scientist to warn that chlorofluorocarbons released into the atmosphere were depleting the earth's critical ozone layer. Research on CFCs and stratospheric ozone eventually led in the 1970s to legislation in the United States, Canada and Scandinavia regulating the manufacture and use of chlorofluorocarbons, and in 1987 to the Montreal Protocol of the United Nations Environment Program, the first international agreement for controlling and ameliorating environmental damage to the global atmosphere. The terms of the Montreal Protocol were strengthened in 1992 to attain a complete phaseout of further CFC production by the year 1996. Rowland has also been investigating the impact of methance gas on the atmosphere. These studies have shown that the atmospheric concentrations increased steadily at about 1% per year from 1978 to 1988, but have reached a near equilibrium in the 1990's. The methane concentration has more than doubled in the past two centuries. Methane absorbs terrestrial infrared radiation, and increases in its concentration contribute to the "greenhouse effect," the gradual warming of the earth's surface. The Rowland research group isnow investigating the hydrocarbon and halocarbon composition of the atmosphere both from aircraft in remote locations and on the surface in hearvily polluted cities. More than 50 scientists have received Ph.D. degrees under his direction.

Dr. F. Sherwood Rowland Dr. F. Sherwood Rowland, the Donald Bren Research Professor of Chemistry, joined the University of California, Irvine, in 1964 as the Department of Chemistry's first chairperson. Dr. Rowland earned his bachelor's degree from Ohio Wesleyan Univer sity and his doctorate from the University of Chicago. Elected in 1994, he is currently the Foreign Secretary of the National Academy of Sciences. A specialist in atmospheric chemistry and radiochemistry, Dr. Rowland and postdoctoral colleague Mario Molina were the first scientists to warn that chlorofluoro carbons (CFCs) released into the atmosphere were deplet -ing the earth's critical ozone layer. Research on CFCs and stratospheric ozone eventually led in the 1970s to legislation regulating the manufacture and use of chlo rofluorocarbons as aerosol propellants in the United States, Canada, and Scandinavia. The 1987 Montreal Protocol of the United Nations Environment Program, as ammended in 1992, became the first international agreement to control and reduce atmospheric damages by banning CFC production after 1995. Measurements of CFCs in the lower atmosphere confirm that the global response to this protocol has been impressive. Another focus of Rowland's work is studying the atmospheric impacts of methane gas and other hydrocar bons­­important contributors to the "greenhouse effect." These studies found that the atmospheric concentrations of methane increased steadily at 1% per year from 1978 to 1988, but have reached near-equilibrium in the 1990s. This data suggests that global methane concentrations have more than doubled in the last two centuries. The Rowland research group is also investigating the hydro carbon and halocarbon composition of urban atmospheres in smog-ladened cities worldwide. Air sampling in Mexico City and Santiago, Chile, found substantial atmospheric concentrations of liquefied petroleum gas (LPG)­­a pre cursor to smog­­leaking from cooking and heating sources.

Kungl. Vetenskapsakademien The Royal Swedish Academy of Sciences The Royal Swedish Academy of Sciences has decided to award the 1995 Nobel Prize in Chemistry to Professor Paul Crutzen , Max-Planck-Institute for Chemistry, Mainz, Germany (Dutch citizen), Professor Mario Molina , Department of Earth, Atmospheric and Planetary Sciences and Department of Chemistry, MIT, Cambridge, MA, USA and Professor F. Sherwood Rowland , Department of Chemistry, University of California, Irvine, CA, USA for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone. Professor Paul Crutzen Professor Mario Molina Professor F. Sherwood Rowland The ozone layer - the Achilles heel of the biosphere The atmosphere surrounding the earth contains small quantities of ozone - a gas with molecules consisting of three oxygen atoms (O ). If all the ozone in the atmosphere were compressed to a pressure corresponding to that at the earth's surface, the layer would be only 3 mm thick. But even though ozone occurs in such small quantities, it plays an exceptionally fundamental part in life on earth. This is because ozone, together with ordinary molecular oxygen (O ), is able to absorb the major part of the sun's ultra-violet radiation and therefore prevent this dangerous radiation from reaching the surface. Without a protective ozone layer in the atmosphere, animals and plants could not exist, at least upon land. It is therefore of the greatest importance to understand the processes that regulate the atmosphere's ozone content.
