Yann LeCun was born on July 8, 1960, in Soisy-sous-Montmorency, a suburb of Paris, France. His early fascination with engineering and science fiction was influenced by his parents; his father was an aeronautical engineer who enjoyed building remote-control cars and airplanes. LeCun pursued his higher education in Paris, where he obtained a Diplôme d'Ingénieur from the École Supérieure d'Ingénieurs en Électrotechnique et Électronique (ESIEE) in 1983, followed by a Diplôme d'Etudes Approfondies (DEA) in 1984 from Université Pierre et Marie Curie, now known as Sorbonne Université. He completed his PhD in Computer Science at the same university in 1987, where he began his pioneering work on machine learning and neural networks. During his doctoral studies, LeCun was deeply influenced by the film "2001: A Space Odyssey," which sparked his interest in artificial intelligence. This interest led him to focus his PhD research on the development of an early form of the back-propagation learning algorithm for neural networks, laying the groundwork for his future contributions to the field.
