Timeline

1900

Theodosius Grigorievich Dobzhansky (Феодо́сий Григо́рьевич Добржа́нский; Теодо́сій Григо́рович Добржа́нський; January 25, 1900 – December 18, 1975) was an American geneticist and evolutionary biologist.

He was a central figure in the field of evolutionary biology for his work in shaping the modern synthesis.

Dobzhansky was born on January 25, 1900, in Nemirov, Russian Empire (now Nemyriv, Ukraine), the only child of Grigory Dobzhansky, a mathematics teacher, and Sophia Voinarsky.

He was given an unusual name, Theodosius, because he was born after his middle-aged parents prayed for a child to St. Theodosius of Chernigov.

1910

In 1910 the family moved to Kiev.

At high school, Dobzhansky collected butterflies and decided to become a biologist.

1915

In 1915, he met Victor Luchnik who convinced him to specialize in beetles instead.

1924

Dobzhansky attended the University of Kiev, where he then studied until 1924 specializing in entomology.

He then moved to Leningrad (today St. Petersburg) to study under Yuri Filipchenko, where a Drosophila melanogaster laboratory had been established.

On August 8, 1924, Dobzhansky married geneticist Natalia "Natasha" Sivertzeva, who was working with Ivan Schmalhausen in Kiev.

The Dobzhanskys had one daughter, known under her married name as Sophie Coe, an anthropologist, food historian, and author, primarily known for her work on the history of chocolate.

Before emigrating to the United States, Dobzhansky published 35 scientific works on entomology and genetics.

1927

Born in the Russian Empire, Dobzhansky emigrated to the United States in 1927, aged 27.

Dobzhansky immigrated to the United States in 1927 on a work–study scholarship from the International Education Board of the Rockefeller Foundation.

Upon arriving in New York City on December 27, he joined the Drosophila Group at Columbia University working alongside Thomas Hunt Morgan and Alfred Sturtevant.

Their work provided crucial information on Drosophila cytogenetics.

Additionally, Dobzhansky and his team helped establish Drosophila pseudoobscura, within the genus Drosophila, as a favorable model organism in evolutionary-biological studies ever since they published their influential works.

Dobzhansky's original mindset (after studying alongside Yuri Filipchenko), was that there were serious doubts on using data obtained from phenomena happening in local populations (microevolution) and phenomena happening on a global scale (macroevolution).

Filipchenko also believed that there were only two types of inheritance: Mendelian inheritance of variation within species, and Non-Mendelian inheritance of variation in a macroevolutionary sense.

Dobzhansky later stated that Filipchenko "bet on the wrong horse".

1930

He followed Morgan to the California Institute of Technology from 1930 to 1940.

On the basis of his experiments, he articulated the idea that reproductive isolation can be caused by differences in presence of microbial symbionts between populations.

1937

His 1937 work Genetics and the Origin of Species became a major influence on the modern synthesis.

In 1937, he published one of the major works of the modern evolutionary synthesis, the synthesis of evolutionary biology with genetics, titled Genetics and the Origin of Species, which amongst other things, defined evolution as "a change in the frequency of an allele within a Gene Pool".

Dobzhansky's work was instrumental in spreading the idea that it is through mutations in genes that natural selection takes place.

Also in 1937, he became a naturalized citizen of the United States.

During this time, he had a very public falling out with one of his Drosophila collaborators, Alfred Sturtevant, based primarily in professional competition.

1940

He returned to Columbia University from 1940 to 1962.

Among his students was geneticist Bruce Wallace.

1941

In 1941, Dobzhansky was awarded the Daniel Giraud Elliot Medal from the National Academy of Sciences, of which he was also a member.

1942

He was elected to the American Philosophical Society in 1942.

1943

In 1943, the University of São Paulo awarded him an honorary doctorate.

1950

He was one of the signatories of the 1950 UNESCO statement The Race Question.

1953

He was elected to the American Academy of Arts and Sciences in 1953.

1964

He was awarded the U.S. National Medal of Science in 1964 and the Franklin Medal in 1973.

1965

Dobzhansky was elected a Foreign Member of the Royal Society (ForMemRS) in 1965.

1970

In 1970, he published Genetics of the evolutionary process.

1971

He then moved to the Rockefeller Institute (shortly to become Rockefeller University) until his retirement in 1971.

1972

In 1972 he was elected the founding president of the Behavior Genetics Association, and was recognized by the society for his role in behavior genetics, and the founding of the society by the creation of the Dobzhansky Award (for a lifetime of outstanding scholarship in behavior genetics).

Dobzhansky's work in the field of evolutionary genetics, with the help of Sewall Wright, integrated standards of the theoretical, natural historical, and experimental work.
