The answer is not easy to determine. There are many factors that go into determining who was the most successful inventor, such as the number of inventions they made, how long their inventions lasted, and how much impact they had on society. In terms of sheer numbers, Leonardo da Vinci stands out as one of the most prolific inventors of all time, with more than 500 inventions credited to him. However, it's difficult to say if he was the most successful because his inventions varied widely in scope and purpose. For example, he created a variety of machines and devices including flying machines, armored tanks, and helicopters.
