Galileo Galilee

Galileo's daughter was essential to his research. She took care of him during his periods of illness and old age, helped him in his research and publishing, and kept him relaxed and ready when he was to go to the inquisition.

When Galileo first started living with his daughter in Florentine, he complained (a lot) of many ailments that he had. It was his daughter who went to the market to get his food, his medicines, and everything he'd need to live on a day-to-day basis. She kept him healthy for him to pursue his scholarly pursuits and do what he did best.

Then, while he was writing his book, she was his number one fan and editor. She read all of his manuscripts, and even though she received little formal education, she knew enough to help him edit things out, modify things, etc. She kept his manuscript tidy and helped make it great.

Finally, when Galileo was called to inquisition, Maria Celeste sent him letters telling him how to behave when it comes to the inquisition. Swallow your pride and do what they tell you do to do. She helped save his life and keep his teachings on track.
