Adolphe Jean-Marie Mouron (1901 – 1968) was a French painter, commercial poster artist, and typeface designer (Cassandre is pseudonym).
He was born in Kharkiv, Ukraine, to French parents. As a young man(1915), he moved to Paris. He studied Impressionism at the Ecole des Beaux-Arts and at the Academie Julian . 

In 1922, he worked of the first advertisement as a Cassandre. The popularity of posters as advertising afforded him an opportunity to work for a Parisian printing house. He earned a reputation with works such as Bucheron (Woodcutter), a poster created for a cabinetmaker and he won first prize at the 1925 Exposition Internationale des Arts Decoratifs et Industriels Modernes. 

In 1926, Cassandre was able to set up his own advertising agency called Alliance Graphique with the help of partners.
He serving a wide variety of clients during in America at the 1930s.
In 1936, his works were exhibited at the Museum of Modern Art in New York City which led to commissions from Harper’s Bazaar to do cover designs. He is perhaps best known for his posters advertising travel, for clients.

His posters are memorable for their innovative graphic solutions. In addition, he taught graphic design at the Ecole des Arts Decoratifs and then at the Ecole d’Art Graphique. 
With typography an important part of poster design, the company created several new typeface styles. Cassandre developed Bifur in 1929, the sans serif Acier Noir in 1935, and in 1937 an all-purpose font called Peignot.

As the World War II begins, Cassandre served in the French army until the fall of France. His business long gone, he worked by creating stage sets and costumes for the theatre. After the war, he continued this line of work while also returning to easel painting.

~Impressions~ I like his works because it is distinctive touch and draws eye. I thought extremely amazing that he was to produce works various genres including typography and painting not only graphic design.
