Lajos Für (21 December 1930, Egyházasrádóc, Hungary–22 October 2013, Budapest) was a Hungarian politician and historian, who served as Minister of Defence between 1990 and 1994. From 1994 to 1996 he was also chairman of the Hungarian Democratic Forum (MDF), the ruling conservative party led by late Prime Minister József Antall to his death in 1993.
From the Hungarian Wikipedia page:
Between 1954 and 1957, he was a deputy lieutenant (he was deprived of his rank in 1956). In 1956 he was the secretary of the Debrecen Kossuth Circle and the Revolutionary Committee of the Hajdú-Bihar County Revolution. He contributed to the formulation of revolutionary demands in Debrecen and he handed them over to the government. After the Revolution was overthrown, he was interned for a short time. He lost his assistantship at the Kossuth Lajos University in 1956 because of his role in 1956, and his research career was stalled. He emigrated to France in 1957, but returned home a few months later. He had no job until 1958 and then worked in a large library of the Reformed College in Debrecen until 1961, after which he was employed for a short period of time. Until 1963 he was a primary school teacher in Dabason and Pestújhely.
