François Robichon de La Guérinière

François Robichon de La Guérinière (1688–1751) was a French riding master who had a profound effect on accepted methods for horse training, and one of the most influential writers on the art of dressage.

In 1715, de La Guérinière received his diploma as an écuyer du roi, and he began as a director of an equestrian academy in Paris, a position which he held for 15 years and which earned him a reputation as an instructor and rider.

This led to an appointment by the Grand écuyer de France, Prince Charles of Lorraine, as Directeur du Manège des Tuileries in 1730.

De La Guérinière is credited for the invention of the shoulder-in, which he called the "alpha and omega of all exercises"; he was the first to describe it.

De La Guérinière states the rider must also have a good seat in order to have a soft, light hand, and makes several references to William Cavendish, 1st Duke of Newcastle.
