Johann Gottfried Moritz (1777 - 23 July 1840) was a German musical instrument builder, best known as one of the inventors of the modern tuba.
[1] Together with Wilhelm Friedrich Wieprecht, the director of the royal military music corps, Moritz was successful in greatly improving the valve system used on early brass instruments.
The oldest remaining original tuba from Johann Gottfried Moritz's workshop is today held in the Musikinstrumenten-Museum Berlin.
In 1835, Johann Gottfried retired from building instruments, with the manufacturing business being taken over by his son Carl Wilhelm Moritz.
Their sons and grandsons kept the business in family hands more or less continuously over the following century and a half, until economic issues following World War 2 forced its closure in 1959.
