Louis Auguste Moreau was born in Dijon, France in 1855 into a family of sculptors. He was the son of Auguste Moreau and brother of Hyppolyte Moreau. His uncles Marthurin Moreau and Hyppolyte-Francois Moreau were also sculptors. He was tutored by his father and also studied at the Ecole des Beaux Arts, Paris. He exhibited at the Paris Salon and also at the Exposition Universelle, winning a number of prizes. He specialised in allegorical and classical groups as well as well-known figures. Moreau went into partnership with his brother Hyppolyte for a time to produce decorative sculptures and created the L&F Moreau signature. He died in France in 1919.

An example of his work can be found in the Perigord Museum of Art, France.
