Answer
Robert of Chester, an English scholar, translated Al-Jabr, an Arabic mathematical treatise by Muhammad ibn Musa al-Khwarizmi, into Latin in the 12th century. This translation introduced the concept of algebra to the Western world, and its title, "Al-Jabr," became the origin of the word "algebra." Al-Jabr was a groundbreaking work that laid the foundation for modern algebra and had a profound impact on the development of mathematics in Europe.
