He was born in Bar-le-Duc to Claude Charles Develle, an insurance agent, and Anne Marguerite Rousselot.
He discovered his passion for political activity as a secretary of Jules Grévy.
Later, once more a simple deputy, he opposed socialism and income tax.
In 1898 he lost an election to the antisemitic nationalist Henry Ferrette [fr], victim of the fallout of the Dreyfus affair, and another in 1899, even more soundly, to another anti-Dreyfus candidate in Louviers.
