Excellent book! The author presents the life of Eli Whitney from birth to death, and all his accomplishments. I found that Eli was more gifted than previously thought and accomplished much more than is covered in simple biographies.
She shows how Eli was mechanical from a young age, and how through perseverence in the many tribulations he faced, he finally reached the success he desired.
The author used the letters and papers from Eli's life to write the biography and inserts their text throughout the biography.
