Antoine Lavoisier

Antoine-Laurent de Lavoisier (August 26 1743 – May 8 1794) was a French nobleman prominent in the histories of chemistry, finance, biology, and economics. He stated the first version of the Law of Conservation of Matter, recognized and named oxygen (1778), disproved the phlogiston theory, and helped to reform chemical nomenclature. Lavoisier is often referred to as the father of modern chemistry. He was also an investor and administrator of the Ferme Générale, a private tax collection company; chairman of the board of the Discount Bank (later the Banque de France); and a powerful member of a number of other aristocratic administrative councils. Due to his prominence in the pre-revolutionary government in France, he was beheaded at the height of the French Revolution.

Execution

As one of 28 French tax collectors and a powerful figure in the unpopular Ferme Générale, Lavoisier was branded a traitor during the Reign of Terror by revolutionists in 1794, and tried, convicted and guillotined all on one day in Paris, at the age of 50. Ironically, Lavoisier was one of the few liberals in his position. One of his actions that may have sealed his fate was a contretemps a few years earlier with the young Jean-Paul Marat, who subsequently became a leading revolutionary.

An appeal to spare his life was cut short by the judge: "The Republic has no need of geniuses ." His importance for science was expressed by the mathematician Joseph Louis Lagrange who lamented the beheading by saying: "It took them only an instant to cut off that head, but France may not produce another like it in a century."

One and a half years following his death, Lavoisier was exonerated by the French government. When his private belongings were delivered to his widow, a brief note was included reading "To the widow of Lavoisier, who was falsely convicted."

About a century after his death, a statue of Lavoisier was erected in Paris. It was later discovered that the sculptor had not actually copied Lavoisier's head for the statue, but used a spare head of the Marquis de Condorcet, the Secretary of the Academy of Sciences during Lavoisier's last years. Lack of money prevented alterations being made and, in any case, the French argued pragmatically that all men in wigs looked alike anyway. The statue was melted down during the Second World War and has never been replaced. Lavoisier's real memorial is chemistry itself.
