Gastev was the chief Soviet proponent of Taylorism, aka scientific management:
In the Soviet Union, Taylorism was advocated by Aleksei Gastev and nauchnaia organizatsia truda (the movement for the scientific organisation of labor). It found support in both Vladimir Lenin and Leon Trotsky. Gastev continued to promote this system of labor management until his arrest and execution in 1939.
The institute he founded and directed till 1937 also did not overlive its creator by long - it was closed down in 1940 (though a rump of it was transferred to the aviation ministry).
Was Gastev's execution part of a general clampdown on scientific management in the Soviet Union during the period (the way Stalin proscribed and presecuted scientists who worked in other fields he disliked, such as genetics and cybernetics) or was it because of other reasons? (He was an "old Bolshevik", that is member of a group which was also singled out by Stalin for elimination).
To be sure, there seems to have been some persecution of the scientific management field:
Во второй половине 1930-х деятельность ЦИТ подвергается критике, прикладные науки о труде обвиняют в идеализме и методологической нейтральности, им навешивается ярлык «буржуазных» наук. Закрываются все лаборатории по промышленной психотехнике и психофизиологии труда, в значительной степени свертывается работа ЦИТа и местных институтов труда (в 1920-х годах их было свыше 10). В 1939 основателя и бессменного руководителя ЦИТ Гастева расстреляли за антисоветскую деятельность.
In the second half of 1930 has been criticized CIT activity, applied science Labour accused of idealism and methodological neutrality, they are labeled as "bourgeois" science. Closes all laboratory and industrial psychotechnics psychophysiology of labor, largely curtailed work ITCA and local institutions work (in 1920 there were over 10). In 1939, the founder and head of CIT Gasteva shot for anti-Soviet activities.
(the quote is from the Russian wikipedia article on CIT).
However, it is not clear whether other people who worked on scientific management were also executed or merely fired.
