His education was entrusted to " ... the most skillful masters at the Capital, where he found himself among the disciples of the celebrated Pere Poré. The student made rapid progress, and was not slow in showing proof of a talent as rare as it was precocious. After successfully completing his classical studies the Collège de Louis-le-Grand, he remained in Paris to attend the School of Law." Voltaire, fifteen years older than Lefranc, attended this school from 1704 to 1711, and was also influenced by Pere Poré.
