Up for sale "Atmospheric Chemist" Harold Johnston Hand Signed First Day Cover Dated 1962. 

American scientist who studied chemical kinetics and atmospheric chemistry. After beginning his academic he was a faculty member and administrator at the University of California,

Berkeley for nearly 35 years. In 1971, Johnston authored a

paper suggesting that environmental pollutants could erode the ozone layer.

Johnston was elected to several scholarly organizations, including the National Academy of Sciences, the American Academy of Arts and Sciences and the American Association for the Advancement of Science. He won

the National Medal of Science in

1997. Johnston was born in Woodstock, Georgia. His

father, Smith Lemon Johnston, helped to run his family's general store. They

lived on a Georgia farm when Harold Johnston was young. In the early 1930s,

Johnston contracted rheumatic fever and

the illness affected his heart. A physician uncle told Johnston's father not to

send Johnston to college because the young man would not survive long enough to

get much use out of the education. Johnston said he later learned that the disease

was associated with an average survival period of fifteen years at the time.

Going to college at Emory University with aspirations of becoming a

journalist, Johnston soon realized that the U.S. was headed toward World War II and that a science degree would serve him

better. Johnston completed an undergraduate degree in chemistry and a minor in

English literature. Johnston received a Ph.D. in chemistry and physics

from the California Institute of

Technology. As a doctoral student, Johnston focused on the

interaction of ozone and the pollutant nitrogen dioxide. While at Caltech, he joined in a secret

defense project that involved protecting the country against the use of gas warfare. From 1947 to 1956, Johnston taught at Stanford

University. While there, he was named to the editorial board of the Journal of

the American Chemical Society In the early 1950s, Johnston

furthered the air pollution work of Arie Jan Haagen-Smit by

showing that free-radical reactions underlay the photochemical process

leading to smog. Throughout his career, much of Johnston's work involved

understanding the kinetics of nitrogen oxides. He returned to Caltech as a faculty

member for a year in 1956. From 1957 until his retirement in 1991,

Johnston was a professor at the University of California, Berkeley. From 1966

to 1970, Johnston was the dean of Berkeley's College of Chemistry. Johnston

mentored undergraduate and graduate students, including future Nobel Prize winner Dudley R. Herschbach and

future National Medal of Science winner Susan Solomon. He also made large contributions to the theory

of elementary chemical reactions.

He wrote a popular textbook on reaction rate theory. Johnston became

best known for his work related to ozone. In a 1971 paper, he posited that pollution

from supersonic aircraft in the stratosphere could deplete the ozone layer. Because

it suggested for the first time that human activity could impact the integrity

of the environment, Johnston's ozone research received some criticism and

resistance. However, two environmental regulatory programs were formed as

a result of his findings – the Climatic Impact Assessment Program (CIAP) and

the Stratosphere Protection Program.
