Sebastiano Bombelli died in 1719.
Sebastiano Bombelli was born in 1635.
The Italian mathematician, Gerolamo Cardano was the first to consider the concept of complex numbers. However, he did not develop a theory of complex numbers to any extent. That was left to Rafael Bombelli.
Rafael Bombelli is usually credited with discovering imaginary numbers in 1572. There were hints of the theory going back much further, perhaps beginning with Hero of Alexandria in the first century.
