Blaise Pascal and Wilhelm Schickard one of those
The inventor of the first successful adding machine is Charles Babbage, who designed the "calculating engine" in the 1820s. However, the first commercially successful adding machine was created by American inventor William Seward Burroughs in 1885. Burroughs' machine utilized a system of keys and a printing mechanism, which made it a significant advancement in mechanical calculators.
Blaise Pascal invented the ancestor of the calculator.
The Hellenistic inventor and mathematician you are referring to is Archimedes. He is well-known for his experiments with levers and for designing the Archimedean screw, a machine used for raising and transporting water. Additionally, Archimedes formulated important mathematical principles, including formulas for calculating the surface area and volume of a sphere. His contributions laid the groundwork for many fields in mathematics and engineering.

Leonardo da Vinci. Experts mean the sketch does not really show an adding machine, but a ratio machine.
William Seward Burroughs made his first adding machine prototype in the early 1880s while working in the Boyer Machine Shop. He filed for his first patent for the calculating-machine in January of 1885, and the patent was issued in August of 1888.

Blaise Pascal invented the ancestor of the calculator.
In 1885 William Seward Burroughs constructed his first calculating machine; though it proved commercially impractical. He patented a practical model in 1892.

John Napier's calculating machine invention is called "Napier's Bones."
the person who invented it was Hugo Caisaguano
Theodore Simpson built the first automatic calculator called the "Calculating Clock" in 1623. Another machine was built by French Mathematician Blaise Pascal in 1642. However , it was William Seward Burroughs who received the first patent for adding machines in August of 1888.
