KENDALLVILLE - No Kendallville High School graduate received more acclaim for his work than Dr. Harold Clayton Urey.

A member of the Class of 1911, Urey became a renowned scientist who won the Nobel Prize for Chemistry in 1934. He later took part in the research leading to the production of the atomic bomb in World War II.

Born April 29, 1893, in Walkerton, he was the son of the Rev. Samuel Clayton and Cora Rebecca (Reinoehl) Urey. His father, a teacher and minister, died when he was 6 years old.

After attending an Amish grade school, Urey attended four years of high school in Kendallville.

According to a high school classmate, the late Marguerite Cramer, as a boy Urey lived in the country near Corunna, but came to live with his uncle in Kendallville for a time so he could attend high school.

Urey had a knack for learning, Mrs. Cramer said in a 1981 interview. His only academic honor prior to attending college was winning a $5 gold piece while attending Kendallville High School, for a speech about his boyhood idol, Theodore Roosevelt.

After high school, Urey taught grade school in Noble County and rural Montana for three years before entering the University of Montana in 1914.

He graduated from the University of Montana with a bachelor of science degree in zoology in 1917.

He spent two years as a research chemist in industry before returning to Montana as an instructor in chemistry.

In 1921 he entered the University of California to work under Professor Lewis and he was awarded the degree of Ph.D. in chemistry in 1923. He spent the following year in Copenhagen at Professor Niels Bohr's Institute for Theoretical Physics as American-Scandinavian Foundation Fellow to Denmark and on his return to the United States he became an associate professor in chemistry at Johns Hopkins University, Baltimore, Md.

In 1929 he was appointed associate professor in chemistry at Columbia University, New York City, and he became professor in 1934.

During the period 1940-1945 he was also director of war research, Atomic Bomb Project, Columbia University. He moved to the Institute for Nuclear Studies, University of Chicago, in 1945 as distinguished service professor of chemistry and became a Martin A. Ryerson Professor in 1952.

He was a visiting professor at the University of Oxford, in England, during 1956-1957 and in 1958 he took a post as professor-at-large, University of California. He held that position until his death in January 1981.

Urey broke into prominence in December 1931, when he announced that in working with two other investigators, research assistant George Murphy and a friend, Ferdinand Brickwedde, Urey had discovered the existence of heavy hydrogen. This discovery is considered one of the most important in the history of modern science, and it was for this discovery that he became a Nobel laureate, which earned him a monetary award of $50,000.

He was teaching at Columbia University at the time. He continued to study the problem of isotope separation and developed the gas distillation process that was successfully used in the creation of the first atomic bomb when the United States and Nazi Germany were in a race for development of the weapon.

A lifelong scientific researcher, Urey served as one of the three program chiefs of the wartime Manhattan Project, which developed the bomb.

His efforts as head of the special alloy materials program of the Manhattan Project were rewarded by President Harry Truman, who presented him the Medal of Merit.

At the end of World War II, Urey joined other scientists in developing theories attempting to explain the way in which the world's original chemical elements united to form the universe.

Among his other significant contributions to science were an oxygen thermometer that makes possible the measure of temperatures in the ancient seas. He also was an adviser to the national space effort and lectured on the subject.

''It's very difficult to tell what the cost of the manned flights to the moon are worth,'' Urey said in a News-Sun interview in 1971. ''Was it worthwhile to build the Parthenon, the cathedrals of Europe - they are of no industrial importance. How much is intellectual activity worth to us? I think it is the most valuable thing there is.''

Urey retired in the beautiful Pacific coastal community of La Jolla, Calif., north of San Diego. At the time of his death at the age of 87, he maintained an office on the nearby campus of the University of California., but spent much of his later years at home writing.

He was survived by his wife, the former Frieda Daum, whom he married in 1926; three daughters and a son.
