Dennis Papin, a French mathematician and physicist, is credited with inventing the "steam digester," the prototype of what we today call the Pressure Cooker, in 1679.
Thomas Savery patented the first crude steam engine in 1698 based on Denis Papin's Digester or pressure cooker of 1679. however the steam engines we know today was invented in 1866

he invented it in 1690
See the link below for information on the Chinese dome digester.

The history of the steam engine stretches back as far as the first century AD; the first recorded rudimentary steam engine being the aeolipile described by Greek mathematician Hero of Alexandria. In the following centuries, the few steam-powered "engines" known were, like the aeolipile, essentially experimental devices used by inventors to demonstrate the properties of steam. A rudimentary steam turbine device was described by Taqi al-Din in 1551 and by Giovanni Branca in 1629. Jerónimo de Ayanz y Beaumont received patents in 1606 for fifty steam powered inventions, including a water pump for draining inundated mines. Denis Papin, a Huguenot refugee, did some useful work on the steam digester in 1679, and first used a piston to raise weights in 1690

1707. The first record is that of a 15 mile trip by steam boat made by Denis Papin, travelling on the Fulda River.
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
During the first century AD, Greek mathematician Hero of Alexandria described the first *recorded) steam engine called the aeolipile. Over the next centuries numerous engines powered by steam were created, notably a steam turbine described by Taqi al-Din (1551) and Giovanni Branca (1629). Similarly, Denis Papin inventred the steam digester (1679), first piston steam engine (1690), first practical steam engine was a water pump invented by Thomas Savery (1698). The first steam engine that was commercially successful appeared in 1712 which combine the works and ideas of many that had come before it in an engine developed by Thomas Newcomen. This was the model that helped spur on the Industrial Revolution. James Watt improved upon Newcomen's model from 1763 to 1775 and created the Early Watt pumping engine, which was more efficent and further accelerated the Industrial Revolution.
