Paul Wintrebert

Paul Wintrebert (1867–1966) was a French embryologist and a theoretician of developmental biology.
He coined the term cytoskeleton ("cytosquelette") in 1931.
He held radical epigenetic views. In his 60s, he published a trilogy in which he describes his position on life process and living being: "Le vivant créateur de son évolution" (The living being is the creator of his own evolution) (1962), "Le développement du vivant par lui-même" (The self-development of the living being) (1963), and "L'existence délivrée de l'existentialisme" (Existence delivered from existentialism) (1965).
He was a critic of the mutationist theory of evolution. His views have been described as a "biochemical Lamarckism".
