Graetz was one of the first to investigate the propagation of electromagnetic energy. The Graetz number (Gz), a dimensionless number describing heat flow, is named after him.[1] Also sometimes known by his name is the diode bridge rectifier circuit that was invented by Polish electrotechnician Karol Pollak in 1896[2] and that was independently invented and published by Leo Graetz in 1897.[3]
In 1880 he confirmed the Stefan–Boltzmann law.[4]
Graetz died in Munich at age 85.
