Maurice Laisant came from a political family. His grandfather was the radical Deputy for Nantes, Charles-Ange Laisant. Maurice and his younger brotherCharles Laisant inherited their libertarian beliefs from their parents. He was initiated into the Free Masons in 1926, joining the "Concordia" lodge of the Grand Orient de France. Normal minimum age requirements were waived because his father was already a member. However, his father died shortly afterwards, on 28 November 1928, and he was required to quit. Despite this unhappy experience he would later defend the Masons from criticism, notably among any fellow anarchists hostile to free masonry. He joined the Young Pacifists' Union in 1935. In 1939 he began working on Le Libertaire, the weekly newspaper which at this time was published by the "Anarchist Union".
Co-founder of the Anarchist federation
After the Second World War ended in May 1945 Maurice Laisant was one of a number of individuals who co-founded, in December 1945, the Anarchist Federation. The co-founders also included Robert Joulin, Maurice Fayolle, Maurice Joyeux, Roger Caron and Henri Bouyé. In 1946 he started to work with Louis Louvet on the anti-militarist weekly publication,. He attended the first congress of the "General Pacifist Federation", held in Paris in November 1946, participating as a member of the propaganda commission. Laisant frequently intervened in support of conscientious objectors even where his personal position on conscientious objection was more nuanced. Maurice Rajsfus recalled a debate on fundamentals within the Anarchist Federation in which Maurice Laisant, while inviting discussion, nevertheless set forth his own point of view with great coherence: Following fragmentation within the Anarchist Federation Maurice Laisant was one of those who set about reconstructing the group in 1953, in the process becoming one of its leading members. In 1956, together with Maurice Joyeux, he joined the editorial committee of Le Monde libertaire, the Federation's magazine. At the start of the 1950s he was a member of "Free Forces for Peace", becoming the group's propaganda secretary in 1952.
The poster affair
In October 1954 Laisant faced charges following the publication of a forceful poster calling for the ending of hostilities in Indo-China. The poster failed to include the requisite legal notice, and it had been printed on white paper. In February 1955 he was condemned by a Paris court and required to pay a large fine. One of those who spoke up for Laisant at his trial was Albert Camus, already an influential supporter of French liberal traditions. Camus told the court: Camus was clearly impressed by the activism of Maurice Laisant.
Later years
In June 1957, at their congress in Nantes, Laisant was appointed Secretary General of the Anarchist Federation, a post he would continue to hold till 1975. In May 1978, after the Ris-Orangis congress at which the Anarchist Federation recognised the class struggle, he took issue with the federation for its drift towards Marxism. With various other groups out of sympathy with this trend, he launched a new edition of :fr:Le Libertaire|Le Libertaire, publication of which had lapsed a few years earlier. It was on the basis of this latest split that in November 1979 he was among the founders of the :fr:Union des anarchistes|Union of Anarchists: he remained a member till he died.
