Johann Heinrich Winckler

The building was enlarged the same year and he wrote the libretto of Froher Tag, verlangte Stunde, a cantata to mark the completion of the project.

[3] In 1744, Winckler authored, Gedanken von den Eigenschaften, Wirkungen und Ursachen der Electricität: nebst einer Beschreibung zwo neuer electrischen Machinen (Thoughts on the Properties, Effects, and Causes of Electricity: Together with a Description of Two New Electrical Machines, 1744).

[1] The Royal Society, which spelled his name Winkler, published information about his electrical experiments in their Philosophical Transactions.

Winckler's textbook Institutiones Philosophiae Universae, published in 1762, drew ethical conclusions from his views on animal souls.

[5] Winckler argued that since animals have sensitive souls, there is no valid reason why it should be permissible to torment them.
