Eise Eisinga (1744 - 1828), was a knitting-wool processor who devoted his spare time to astronomy and mathermatics. When the announcement of a May 1774 conjunction of the Moon, Mercury, Venus and Jupiter in the same constellation spread panic among Europe's unenlightened (who thought it was a fearsome omen of Armageddon), Eisinga was shocked to see how unneccessary anquish sheer ignorance could cause. He announced to his wife that he was going to educate the public by building a planetarium in the back room of their house.
His first hurdle was to overcome the disparity between the regularity of clockwork and the actual celestial movements overhead, and he was the first to solve this old problem. Another difficulty was squeezing the wheel mechanisms between the ceiling of the room and the beams support the attic floor. A particular annoyance to Eisinga's wife was the combination pendulum-bedstead, which had to do its work partly in the conjugal sleeping accommodation.
Eisinga completed the project in 1781. In 1858, thirty years after his death, the house was handed over to the town of Franeker on condition that it would be opened to visitors, kept up, and the workings of the planetarium explained. In all respects, the town has been faithful to its obligations.
