Otto Effertz

Born in 1856 from a German father and a Dutch mother, he graduated in medicine, but later engaged in economics studies, without obtaining academic titles in Germany.^[1]

He then moved to France, where he published many of his works. After moving to Mexico, he studied mathematics, returning to Germany in 1912. He was again in France in 1913, where he held some lessons thanks to the support of Charles Gide, Adolphe Landry and the Revue socialiste.^[1]

Kept prisoner at the beginning of World War I by the French, he was released only at the end of the conflict. He spent his last years in Düsseldorf, where he died in 1921.^[1]

He elaborated his own form of socialism, in which he wanted to take into account that goods do not take their value only from work but also from land.^[2][3][4]
