Johann Kaspar Lavater

Johann Kaspar (or Caspar) Lavater (15 November 1741 – 2 January 1801) was a Swiss poet, writer, philosopher, physiognomist and theologian.

Lavater was born in Zürich, and was educated at the Gymnasium there, where J. J. Bodmer and J. J. Breitinger were amongst his teachers.

At barely twenty-one years of age, Lavater greatly distinguished himself by denouncing, in conjunction with his friend Henry Fuseli the painter, an iniquitous magistrate, who was compelled to make restitution of his ill-gotten gains.

In 1769 Lavater took Holy Orders in Zurich's Zwinglian Church, and officiated until his death as deacon or pastor in churches in his native city. His oratorical fervor and genuine depth of conviction gave him great personal influence; he was extensively consulted as a casuist, and was welcomed with enthusiasm on his journeys throughout Germany. His writings on mysticism were widely popular as well.

In the same year (1769), Lavater tried to convert Moses Mendelssohn to Christianity, by sending him a translation of Charles Bonnet's Palingénésie philosophique, and demanding that he either publicly refute Bonnet's arguments or convert. Mendelssohn refused to do either, and many prominent intellectuals took Mendelssohn's side, including Lichtenberg and Herder.

Lavater is most well known for his work in the field of physiognomy, Physiognomische Fragmente zur Beförderung der Menschenkenntnis und Menschenliebe, published between 1775 and 1778. He introduced the idea that physiognomy related to the specific character traits of individuals, rather than general types.
