Origins & Early Life

Pierre Guillaume Frédéric le Play (French: [pjɛʁ ɡijom fʁedeʁik lə plɛ]; April 11, 1806 – April 5, 1882) was a French engineer, sociologist and economist. The son of a custom-house official, Le Play was educated at the École Polytechnique and the École des Mines. He took an interest in sociological questions even as a young man at the École des Mines, befriending a follower of the socialist thinker Saint-Simon. In the late 1820s, Le Play undertook an immense walking tour of Germany investigating its mines.

Pivotal Works & Achievements

In 1830, a laboratory accident seriously damaged Le Play's left hand and left him disabled for life. While he was recovering in Paris, he was a witness to the events of the July Revolution, and thereafter resolved himself to studying the issues that plagued French society. In 1834, he was appointed chairman of the permanent committee of mining statistics. He spent the remainder of the 1830s traveling the backroads of Europe as a mining expert, and conducting empirical studies on the state of mines and their workers. In 1840, he became engineer-in-chief and professor of metallurgy at the École des Mines, and was made inspector in 1848.
