Marcel Alexandre Bertrand(2 July 1847 – 13 February 1907) was a Frenchgeologistborn inParis.He was the son ofmathematicianJoseph Louis François Bertrand(1822–1900), and son-in-law tophysicistÉleuthère Mascart(1837-1908).
He studied at theÉcole Polytechnique,and beginning in 1869 he attended theEcole des Mines de Paris.From 1877 he carried out geological mapping studies ofProvence,theJura Mountainsand theAlps.In 1886, he became an instructor at theÉcole Nationale Supérieure des Mines,and in 1896 became a member of theAcadémie des sciences.
Bertrand, a founder of moderntectonics,originated anorogenic"wave theory" of mountain-building and introduced[when?]thenappehypothesis (nappe de charriage). His wave theory described a build-up of massive folds of earth taking place over successive geological eras, called theCaledonian,HercynianandAlpineperiods of orogeny. Bertrand later added a fourth event called theHuronian orogeny,which took place 2400 to 2100 million years ago, inPrecambriantime.
In 1890 he was named president of theSociété géologique de France.[1] TheConcours de Géologietwice awarded him thePrix Vaillant(1886 and 1890); he also won thePrix Fontannes(of the Société géologique de France) in 1888 and thePrix Petit d'Ormoyin 1893.

He was married to Mathilde Mascart and their daughter,Thérèse Bertrand-Fontaine(1895 – 1987), became a physician and researcher. She was only the third woman to be named a full member of the National Academy of Medicine.[2]
