Paul Lambert (21 February 1912 – 17 September 1977) was a Belgian cooperator and professor of economics at the University of Liège.
[3] When Belgium was invaded in 1940 by Nazi Germany Lambert was conscripted and subsequently spent five years as a prisoner of war, which he recounted in his 1946 book Hommes perdus à l’Est ("Men Lost in the East").
He returned to academia after the war, later becoming chair of political economy at the law faculty of the University of Liège.
[3] In 1959 he authored La Doctrine coopération, an influential overview and history of the ideas and the economics of the co-operative movement.
The work was translated into English as Studies in the Social Philosophy of Co-operation (1963).
