"George Gamow".
The following 4 books are 'must read' (that cover related fields too):
Biography of Earth
Birth and death of Sun
Creation of Universe
One, two, three, infinity.
Amongst celebrated astronomers: Flamstead, Baker (whose text was my first astronomy book), Harlow Shapely, Harold Spencer Jones ('Life on other worlds'), Patrick Moore, Robert Burnham's 3 volume set (the best on Astronomy), Prof S. Chandrasekar if you want highly serious stuff.
If one has 'Cambridge Encyclopedia of Astronomy', nothing more is needed.
