The physical units of frequency (oscillation) are cycles per second (e.g., 60 cycles per second), but the metric (or SI) unit of Hertz is also used for frequency (e.g., 60 Hertz). The SI unit of frequency is named after Heinrich Hertz (1857-1894), a physicist who was born in the city of Hamburg, Germany.
