Johann Andreas Benignus Bergsträsser

Johann Andreas Benignus Bergsträsser (21 December 1732, in Idstein – 24 December 1812, in Hanau) was a German educator, philologist, and entomologist.

Education
He studied philology and theology at the universities of Jena and Halle, and in 1756–58 worked as a teacher at the orphanage in Halle an der Saale. In 1760 he was appointed rector at the Evangelical Lutheran gymnasium in Hanau. In 1775 he obtained the title of professor and became a member of the consistory.

In 1784 he proposed a type of optical telegraph system to "connect" Leipzig with Hamburg. He initially tried a variety of other types of fire-related communications. But this connection used four different types of rockets: rockets without detonation; rockets with detonation; illuminating signal rockets and firework rockets.
