La Roche, Estienne de [Villefranche]
- 1. Dates
- Born: Lyon, c. 1480
- Died: fl. Lyon, c. 1520
- Dateinfo: Flourished (two dates give known period)
- Lifespan: N/A
- 2. Father

- No information on financial status.
- 3. Nationality
- Birth: French

- 4. Education
- Schooling: No University
- He may have been a pupil of Nicolas Chuquet. There is no evidence that he attended a university or that Chuquet taught at any university.
- 5. Religion
- Affiliation: Catholic (assumed)
- 6. Scientific Disciplines
- Primary: Mathematics
- His fame rests solely on his Larismetique published in 1520. This work introduced into France the Italian knowledge of arithmetic and useful notions of powers and roots. In 1880 Aristide Marre published Chuquet's Triparty which only existed in manuscript form and suddenly La Roche was a plagiarist. Recent scholarship, though agreeing that parts of the Triparty were blatantly copied and other parts suppressed or curtailed in La Roche's Larismetique, has emphasized the audience that La Roche was trying to reach with his work. At worst La Roche can be accused of patching together the works of three authors, Luca Pacioli, Philippe Frescobaldi (a banker in Lyon), and Nicolas Chuquet, whose works were inaccessible to the average French merchant. La Roche simply made their information available to a previously neglected audience.
- 7. Means of Support
- Primary: Schoolmastering
- He taught arithmetic for twenty-five years in the commercial center of Lyon. He was called the "master of ciphers."
- 8. Patronage
- Type: None
- He apparently possessed the manuscripts of both Chuquet and Frescobaldi, but I see no reason, without more information, to chalk this up as patronage.
- 9. Technological Involvement
- Type: Applied Mathematics
- 10. Scientific Societies
- Memberships: None
