Joseph Bruseau de La Roche
Joseph Bruseau de La Roche(? in Paris – 17 July 1750 in Brussels) was an 18th- century French actor, playwright and theatre manager.
Joseph Bruseau La Roche directed the Théâtre de la Monnaie from 1731 to 1733, a job that had previously been handled by Jean- Richard Le Roux.
The theater knew several successful performances under his guidance, but also endured harsh competition by the Théâtre du Coffy.
La Roche relinquished the position in 1733, but remained in contact with the theater throughout his acting career.
He was succeeded by François Moylin.
La Roche composed several theatre plays:
During the 1740s, La Roche was a seller of wallpaper and tapestries.
Guy I de la Roche
Guy I de la Roche (1205–1263) was the Duke of Athens (from 1225/34), the son and successor of the first duke Othon.
After the conquest of Thebes, Othon gave half the city in lordship to Guy.
Othon de la Roche
Othon de la Roche, also Otho de la Roche (died before 1234), was a Burgundian nobleman of the De la Roche family from La Roche-sur-l'Ognon.
He joined the Fourth Crusade and became the first Frankish Lord of Athens in 1204.
In addition to Athens, he acquired Thebes by around 1211.
Frederick de la Roche
Frederick de la Roche( died 30 October 1174) was the sixth Latin archbishop of Tyre( 1164 – 1174), chancellor of the kingdom of Jerusalem( c. 1150), and the chief diplomat of King Amalric I.
He was a Lorrainer, from the town of La Roche, of noble stock.

Isabella de Beaumont

Estienne de La Roche
Estienne de La Roche( 1470 – 1530) was a French mathematician.
Sometimes known as Estienne de Villefranche, La Roche was born in Lyon, but his family also owned property in Villefranche- sur- Saône, where he lived during his youth.
He studied mathematics with Nicolas Chuquet.
Having in his possession Chuquet's manuscripts, it is probable that La Roche was on good terms with Chuquet.
He taught commercial mathematics in Lyon for 25 years.
He is regarded today as a professor of arithmetic( at the time, Master of Figures).
In 1520, he published" l'Arismetique", regarded at the time as an excellent handbook of algebra using an elegant notation for powers, square roots and roots of a higher nature.
However, in 1880, Aristide Marre published the book" Triparty" by Chuquet, and it proved that the first part of" L'arismetique" was essentially a copy of the algebra of Chuquet.
La Roche did try to teach significant mathematics, inaccessible at the time to a French audience, and thus was not merely a plagiarist.
He was the worthy successor of several masters and experts in his art, such as Luca Pacioli.
La Roche may have borrowed from or been influenced by several mathematicians, including Chuquet, Pacioli and Philippe Frescobaldi, a French banker who wrote some books of mathematics.
Joseph de La Roche Daillon
Joseph de La Roche Daillon( died 1656, Paris) was a French Catholic missionary to the Huron Indians and a Franciscan" Récollet" priest.
He is best remembered in Canada as an explorer and missionary, and in the United States as the discoverer of oil near the Allegany River.
He was the son of Jacques de La Roche, seigneur of Daillon in Anjou, and of Jeanne Froyer of La Baronnière.
La Roche's career as a missionary lasted less than five years in the 1620s.
