Girolamo Cardano is known best for his discoveries in mathematics, which included the solution to the cubic equation. The cubic equation was actually founded by Tartaglia, and told with secrecy to Cardano. Cardano developed the solution further and called it his own.
The Archbishop of Scotland who thought he was suffering from consumption, sent for Cardano to come and cure him. With Cardano’s help, he made a complete recovery from consumption, which he was not suffering from.
He found this subject interesting because his oldest son was deaf in one ear and Cardano, himself, had a problem with stuttering.
“The writing is connected to speech and the thought, but written letters and ideas could be brought together without the participation of read sounds.”
Although Cardano wrote about the deaf being able to learn even thought they had no verbal communication, he never went further to study it.
