liquid fuel
Dr. Robert H. Goddard a New England physics professor created the first liquid fuel rocket using liquid hydrogen and liquid oxygen, the same fuels used today to power the space shuttle main engines.
Robert Goddard invented the first liquid-fueled rocket engine in 1926. The liquid fuel he used was a combination of gasoline and liquid oxygen. This innovation paved the way for modern rocket technology.
The three types of rocket fuels are liquid rocket fuel, solid rocket fuel, and hybrid rocket fuel. Liquid rocket fuel consists of liquid components that are combined and ignited to produce thrust. Solid rocket fuel is a mixture of solid components that burns to produce thrust. Hybrid rocket fuel combines elements of both liquid and solid rocket fuels.
There are solid rocket fuels, and there are liquid rocket fuels.

liquid Hydrogen + liquid Oxygen
A liquid-fuel rocket or a liquid rocket is a rocket with an engine that uses propellants in liquid form.
Robert H. Goddard made the first liquid fuel rocket the first solid fuel rocket was by the Chinese as early as 1000 ad
liquid Hydrogen + liquid Oxygen
Robert Goddard created and launched the first liquid fueled rocket on March 16, 1926. This was the origin of rocketry as we know it today. For this he is called the father of modern rocketry.
It uses fuel which is in the liquid state.
