Moses Gomberg (February 8, 1866 – February 12, 1947) was a chemistry professor at the University of Michigan.

He was born in Yelisavetgrad, Russian Empire. In 1884, the family emigrated to Chicago to escape the pogroms following the assassination of Czar Alexander II. In Chicago he worked at the Stock Yards while attending Lake High School. In 1886, Moses entered the University of Michigan, where he obtained his B.Sc in 1890 and his doctorate in 1894 under the supervision of A. B. Prescott. His thesis, titled "Trimethylxanthine and Some of its Derivatives", dealt with the derivatization of caffeine.

Appointed an instructor in 1893, Gomberg worked at the University of Michigan for the duration of his professional academic career, becoming chair of the Department of Chemistry from 1927 until his retirement in 1936. Dr. Gomberg served as President of the American Chemical Society in 1931.

In 1896–1897, he took a year's leave to work as a postdoctoral researcher with Baeyer and Thiele in Munich and with Victor Meyer in Heidelberg, where he successfully prepared the long-elusive tetraphenylmethane.

During attempts to prepare the even more sterically congested hydrocarbon hexaphenylethane, he correctly identified the triphenylmethyl radical, the first persistent radical to be discovered, and is thus known as the founder of radical chemistry. The work was later followed up by Wilhelm Schlenk. Gomberg was a mentor to Werner Emmanuel Bachmann who also carried on his work and together they discovered the Gomberg-Bachmann reaction. In 1923, he claimed to have synthesized chlorine tetroxide via the reaction of silver perchlorate with iodine, but was later shown to have been mistaken.
