Pierre Biétry

Pierre Biétry (9 May 1872 – 3 December 1918) was a French syndicalist and politician who initially followed orthodox socialism before pioneering the "Yellow socialist" movement of the early 20th century.

[4] His break with socialism occurred around then, largely as a result of his opposition to the idea of a general strike as well as his overall disillusionment with the failure of socialist activity in France.

[5] Initially the new movement was fairly low-key, but it gained a surge in support in 1910-11 after a series of violent acts by the Confédération générale du travail led to many more conservative workers deserting their ranks.

[7] According to his grandson Pierre Salinger, he was a deputy at the French National Assembly from 1906 to 1910, where his "highlight" was his "vigorous" and "heated" defense of Alfred Dreyfus when the latter was (falsely) accused of stealing military secrets.

[8] His Jaunes movement surprisingly won the support of traditionally-conservative figures such as Victor Henri Rochefort and Paul Déroulède who were attracted to Biétry's patriotism as well as Drumont.
