In Walter Isaacson's book "The Innovators," he explores the multifaceted personality of Charles Babbage, who played a significant role in the early stages of computing. While Babbage could be affable and engaging when he chose to be, he was also known for his difficult traits such as stubbornness and defiance. This complexity is common among many innovators throughout history, who often possess both charming and challenging characteristics.

Isaacson's portrayal of Babbage underscores the idea that great inventors are not just defined by their achievements, but also by their dynamic personalities. This duality can drive creativity and innovation, even as it sometimes leads to conflict or misunderstanding in their collaborations. Hence, the interplay between Babbage's charm and his more difficult attributes illustrates the intricate nature of invention and the individuals behind it.
