Francesco Comelli
Francesco Comelli (1744 in Parigi – 1816 in Bologna)[1] was an Italian scientific instrument maker with considerable expertise in foundry and metalworking.[2]
Comelli was a skilled craftsman who made machines, instruments, and clocks, and an innovator in the design of metal presses.[3] In 1780 he was appointed "regulator" of the public clock in Bologna.[2] A device designed by Comelli was used by Gianbattista Guglielmini in experiments to measure the rotation of the earth in 1791.[4]
