The nouns Stakhanovism and Stakhanovitism designate a movement, developed in the Union of Soviet Socialist Republics in 1935, aimed at encouraging hard work and maximum output, following the example of the coal-miner Alexei Stakhanov (1906-1977).

Note: While the noun Stakhanovism is composed of the name Stackhanov and of the suffix -ism, the noun Stakhanovitism is probably composed of Stakhanovit- in the word Stakhanovite (used as a noun and as an adjective) and of the suffix -ism.

In extended use, the nouns Stakhanovism and Stakhanovitism designate:
– (complimentarily) exceptionally productive work;
– (disparagingly) excessively intensive work.

An extended use of the noun Stakhanovitism occurred, for example, in a review of two books by the British urbanist Peter Hall (1932-2014), Cities of Tomorrow (Oxford: Blackwell Publishing, 1988) and London 2001 (London: Unwin Hyman, 1989)—review by Hugh Freeman, published in The Daily Telegraph (London, England) of Saturday 4^th February 1989 [No. 41,559; weekend supplement: page XIII, column 6]:

The Olympian disdain for ordinary people explains much of the suspicion inspired by planning, especially in Britain, where the continuity of things has attached long memories to almost every house and field. Peter Hall, author of Cities of Tomorrow (not he of the National Theatre), believes that much of this odium really belongs more to architects than to planners.

In a burst of literary Stakhanovitism, the same author has also produced a 25-year sequel to his well-known London 2000 ¹.

¹ Peter Hall’s London 2000 was first published in 1963 by Faber & Faber, London.

The earliest occurrences of the noun Stakhanovism that I have found are from a special cable to The New York Times and The Gazette, by the British journalist Walter Duranty (1884-1957), published in The Gazette (Montreal, Quebec, Canada) of Tuesday 17^th September 1935 [Vol. 164, No. 223, page 1, column 5]:

Moscow, September 16.—The past month witnessed an extraordinary phenomenon in the Donetz coal field whereby the output of one coal miner with an automatic hammer has been pushed up from the “normal average” of five tons per six-hour shift to the fantastic figure of 310 tons. The social and economic consequences of this achievement bid fair to be not less remarkable than the achievement itself.
It all began with a 22-year-old youngster named Stakhanov, son of a Donetz coal miner, who, after two years training in the technical institute, began work last spring as a cutter with an automatic tool. Stakhanov came to the conclusion that the rate of cutting could be improved and invoked a new method. The scheme attracted the attention of the authorities and got wide publicity, even in the Moscow press, and other mines adopted “Stakhanovism” as it now is called.
Records fell like leaves from day-to-day—100 tons—200—and 250, until finally a miner named Artukhof with three loaders and two proppers reached 310 tons which netted for each of them 540 rubles pay for six hours’ work (the monthly salary of a full professor in the U.S.S.R. is 600 rubles). At this point the Commissar of Heavy Industry and Politburo member, Mr. Ordjenikidze, weighed in with a letter of encouragement and a leading organ of the Soviet press made Stakhanovism a front page feature.

The earliest occurrences of the noun Stakhanovitism that I have found are as follows, in chronological order:

1-: From Foreign News, published in The Detroit Free Press (Detroit, Michigan, USA) of Thursday 31^st October 1935 [105^th Year, No. 180, page 4, column 2]—this text also contains the earliest occurrence of the word Stakhanovite (here used as a noun) that I have found:

New God for Russia

MOSCOW—Man’s “God-given right to be inefficient” was put under the interdict in all the Soviet Republics Wednesday by a Government decree which warned the proletariat to stop popular sabotage against the rising cult of Stakhanovitism.
Stakhanovitism, the latest Movement in Russia, is sweeping the country with almost religious fervor. Become a Stakhanovite, the proletariat is told, and do twice as much work as you could before.
The cabala of the order is a closed secret, but thousands of testimonials in the press and at corner revival meetings say that through a system of “muscular rationalization” it can triple, or even quintuple, man’s capacity for getting things done.
It started as a fad but by this time has so impressed the Government that its universal application is envisioned, and Moscow is confident of soon being able to complete a five year plan every eighteen months.
Alexey G. Stakhanov, a coalminer who invented the system, mined only six tons of coal a day before he adopted it, but now he and an assistant produce over one hundred tons daily, official reports assert.
Spreading from Stakanhov’s [sic] coal mines, the method is now applied in various fields of industry, but simultaneously there have been attacks on introducers of the system.
Two persons were arrested at Serpukhov, in Moscow Province, for beating up a ditchdigger who doubled his ordinary results by use of the system.
It has been announced that, due to the Stakhanov Movement, the country will receive 50,000 centners (about 5,500,000 pounds) more of meat per year than had been expected, about 80,000 centners more of dairy products, about 33,000 centners more soap, about 700,000,000 more cigarets and more cabbages and lumber.

2-: From Russ Envision New Era, published in The Windsor Daily Star (Windsor, Ontario, Canada) of Tuesday 19^th November 1935 [Vol. 35, No. 66, page 20, column 6]:

MOSCOW, Nov. 19.—The Russian Government yesterday flatly announced that it had found a short-cut to Utopia.
IN an amazing decree delivered before the National Stakhanovite Congress which opened in the Kremlin, Dictator Josef Stalin ² pledged the Soviet Government to the strangest of all new deals, whereby:
1—One man will be able to do the work of 50.
2—The ruthless Socialistic dictatorship which now rules will be replaced by true Communism, whereby every worker’s day will consist mainly of leisure hours.
3—Great national wealth will be equally shared.
All this is to be accomplished through a movement known as Stakhanovitism. Just what this mouth-filling “ism” means is somewhat beyond Occidental comprehension, but foreign observers here declared that through it Russia has at last found a religion to replace the Orthodox Church which Communism swept away.

² Joseph Stalin (Iosif Vissarionovich Dzhugashvili – 1879-1953), General Secretary of the Communist Party of the Union of Soviet Socialist Republics from 1922 to 1953.

Stakhanovitism

THE appearance of Stakhanovitism in Soviet Russia is not remarkable merely because it is an outbreak of mysticism with wonder-working features.
The Eastern Slavs have a deeply ingrained instinct for that sort of thing. It is born of their blood and their environment. The history of the Muscovites is well tinctured with accounts of mystical movements and magical phenomena.
Mysticism was a considerable basis of the religion of the Romanoff days, a fact that helps explain its divorcement from reality.
The real peculiarity of Stakhanovitism is its manifestation through the medium of industrialism, the founder of the movement being a coal miner who started the ball rolling by reporting that he had been able to augment his normal daily output about 15 times while under an inspired spell.
According to the accounts, converts to the cult now find themselves able to do miraculously large amounts of work; and are commencing to look forward to a time when the labor of the land can be done in a few hours each week and the greater part of life spent lolling in a sort of terrestrial paradise.
An explanation of this peculiar, large scale association of mysticism and industrialism probably is to be found in the insistence with which for several years M. Stalin has been undertaking to make industrial efficiency and advancement the ruling passion of Red Russia.
The Five-Year Plan and the other plans that have followed it have been holy gospels, with heretics risking death at the hands of professional government maintained assassins.
Industrial efficiency has been imposed as a substitute for religion.
But the Slav mind simply cannot rationalize life and its activities for any length of time. The visionary, the magical, the occult and the mystical are never far in the background of the consciousness of even the most cultured Russian, when he is typical.
And if these things cannot burst through into the foreground in one way, they must in another.
With the ancient faith in eclipse, they demand expression in the new. If Industrialism is to be the new God, it must produce its signs, wonders and miracles. This at least, seems to us a reasonable first view explanation of what is occurring in Russia.
The explanation of the way in which Stalin has accepted Stakhanovitism may be another matter.
It is difficult to believe that the impassive man of steel has “fallen for it”; but he does know his fellow Russians, and in the past he has shown himself a consummate opportunist.
If he is cold bloodedly undertaking to direct a new movement, he probably could not suppress, for the advancement of his own particular purposes, he will be acting consistently with his general record.
