Who is Leopold Bloom from Ulysses and what is their importance?

Leopold Bloom is a thirty-eight-year-old canvasser, who lives with his wife Marion in Dublin. He is described as an empathetic, sensitive, earthy, sensual person who responds to the weather, to the smell of organ meat cooking, to women he sees on the street, and who puzzles over laws of physical science. Leopold loves his daughter Milly dearly and continues to mourn for his son Rudy, who died as an infant.
