Deaths by improvised explosive device

René Marx Dormoy (French pronunciation: [ʁəne maʁks dɔʁmwa], 1 August 1888 – 26 July 1941) was a French socialist politician, noted for his opposition to the far right. Under his leadership as Minister of the Interior in the government of Léon Blum, the French police infiltrated La Cagoule, which was planning the overthrow of the French Third Republic, led by the Popular Front government. Dormoy directed the arrest and imprisonment of 70 cagoulards in November 1937. The police recovered 2 tons of armaments from their sites.
After the Occupation of France, Dormoy as a representative refused to approve providing full powers to Marshal Philippe Petain and the Vichy government. He was arrested in 1940 and interned in house arrest in Montélimar. He was assassinated there in July 1941 by a bomb set off at his house. It was believed to be the work of La Cagoule terrorists.

Giangiacomo Feltrinelli (Italian: [dʒanˈdʒaːkomo feltriˈnɛlli]; 19 June 1926 – 14 March 1972) was an influential Italian publisher, businessman, and political activist who was active in the period between the Second World War and Italy's Years of Lead. He founded a vast library of documents mainly in the history of international labour and socialist movements.
Feltrinelli is perhaps most famous for his decision to translate and publish Boris Pasternak's novel Doctor Zhivago in the West after the manuscript was smuggled out of the Soviet Union in the late 1950s. He died violently under mysterious circumstances in 1972.
