a German mathematician and astronomer who may have set up the first observatory in the city of Strasbourg. Reichelt traveled through Northern Europe some time after 1666 and met other notable 17th century scientists and thinkers. After his return from his trip Reichelt may have proposed the building of the "turret lantern" as an astronomical observatory at the top of Strasbourg's Hospital Gate based on the Rundetårn (Round Tower) he saw in Copenhagen.
