Jacques Auguste Weismann was born on 18 September 1878 in Paris and died on 21 July 1962 in Saint-Germain-en-Laye. He was the son of Théophile Gottlieb Weismann and Emma Pauline Koenigswerther and he married Marthe Bickart on 7 May 1908.
Jacques was a French painter, pastellist, illustrator and sculptor. A student of Fernand Cormon, Paul-Émile Boutigny and Ferdinand Humbert. From 1905 onwards, he exhibited at the Salon des Artistes Français, winning the silver medal in 1923 and the gold medal in 1932. He was made a Knight of the Legion of Honour in 1930.
He exhibited his portraits, pastels and paintings at the Salon des Indépendants, the Salon d'automne, the Salon d'hiver, the Maison des Artistes at 152, Boulevard Haussmann in Paris and the Simonson gallery. Among his best-known works are the portraits of Marshal Foch, painted in 1921 and exhibited at the Palais du Luxembourg, and of General Gouraud, as well as those of the stars of the day, such as Tino Rossi, whose portrait he exhibited in 1937, and that of Jeanne Aubert in 1939.
He also participated in the Salon des Artistes Français on 17 May 1940. With the discriminatory statute against the Jews of the Vichy regime during WWII it is possible that this artist later signed under the name of Jack Weiz. He lived at 11 boulevard Pereire in the 17th arrondissement of Paris.
