He was considered one of the most promising young theoretical physicists, alongside colleagues like Lev Landau, who moved to Kharkov in 1932, George Gamow, and Dmitri Ivanenko.

He also lectured on nuclear physics, the second major research focus of the institute, where he was assigned to the relevant group led by Ioffe and Kurchatov from 1932 onward.

At that time, a campaign against modern physics was underway in the Soviet Union, temporarily stripping even prominent theorists like Igor Tamm and Leonid Mandelstam of their teaching privileges.

Bronstein also engaged in practical research, publishing a paper on an electromagnetic method for measuring an aircraft’s speed, which received Kurchatov’s approval.

The initial idea for this framework came from Lev Landau, Dmitri Ivanenko, and George Gamow, though Bronstein developed it further in his theoretical work.

In August 1937, while he was living in his apartment at 38 Rubinstein Street, St. Petersburg, Bronstein was arrested after having had his legs broken by his captors as part of the Great Purge.

Bronstein's books for children "Solar Matter" (Солнечное вещество), "X Rays" (Лучи X), "Inventors of Radio" (Изобретатели радио) were republished after his reputation had been rehabilitated posthumously on 9 May 1957.

The Bronstein Prize in Loop Quantum Gravity is offered to post-doctoral scholars in the field,[3] the inaugural winner of which was Eugenio Bianchi in 2013.

Bronstein chose to describe spectral analysis, but it took many attempts as well as Marshak's advice to determine the best plot in which the story could relate to the history of helium.
