Isidore Jules Bonheur (1827–1901) was a French sculptor renowned for his dynamic and lifelike animal bronzes, particularly those depicting horses, cattle, and other domestic and wild animals. Born in Bordeaux into an artistic family, Bonheur was the younger brother of the celebrated painter Rosa Bonheur. He studied at the École des Beaux-Arts in Paris and exhibited regularly at the Paris Salon, establishing himself as a leading figure in 19th-century French animalier sculpture.

Bonheur’s works are distinguished by their meticulous observation of anatomy and movement, capturing both the physical structure and the character of his subjects. He often cast his figures in bronze, producing small- and medium-scale works that were highly sought after by collectors and institutions alike. His ability to combine realism with expressive form placed him among the most respected animal sculptors of his era.

Throughout his career, Bonheur received numerous awards and honors, including medals at international exhibitions, which affirmed his prominence within the French artistic establishment. His sculptures were appreciated not only for technical skill but also for their vitality and narrative quality, often portraying animals in naturalistic settings with a sense of drama and energy.

Today, Isidore Bonheur is remembered as one of the foremost animalier sculptors of 19th-century France. His works remain prized for their combination of precise naturalism, artistic sensitivity, and enduring aesthetic appeal.
