A career military man, Thomas Victor, befriended by the Barbizets, married one of their daughters. In 1876 he changed his profession and, enthusiastically, set up his workshop at 106 avenue d'Orléans, in Montrouge, south of Paris, where he had a very productive and flourishing career for about ten years. His style at first was quite close to that of his father-in-law Barbizet, and confusion still sometimes remains between the productions of the two workshops. Sergent quickly excelled in the art of ceramics and exhibited, like his colleagues, in 1873 at the Vienna International Exhibition, in 1874 at the London International Exhibition, in 1878 at the Paris World's Fair where he won the bronze medal, and in 1883 at the Amsterdam International Exhibition. 

He is a conscientious and extremely productive artist. He creates original forms and compositions, from the largest to the smallest subject. Thomas Victor perfects a very plastic paste; his colors are luminous, contrasted and more vivid and varied than those of his colleagues, while keeping this aspect of softness and melting that characterizes him. His enamels are deep with beautiful effects of jasper, often mixed with blues and browns. His bestiary is vigorously modeled and molded and his style is expressive.
