The New Israelite Temple Society was founded in 1817. One of the pioneers of the Temple movement was Israel Jacobson (1768–1828). In 1810 he founded his school synagogue in Seesen, and Kassel.

The Hamburg Temple was first invented in 1818 in the Brunnenstraße (Hamburg Neustadt).
The religious service of the Hamburg Temple was disseminated at the 1820 Leipzig Trade Fair where Jewish businessmen from Germany, many other European countries, and from the USA met and discussed the new ritual. As a consequence, the Reform community, including New York and Baltimore, adopted the Hamburg Temple's new prayer book, which was read from front to back, as in the Christian world.
