Who was Lady Godiva?

On July 10, 1040, Lady Godiva rode naked on horseback through Coventry, according to legend, to force her husband, the Earl of Mercia, to lower taxes. An excerpt from the article:

"You might associate the name “Godiva” with a brand of Belgian chocolates, but it was first popularized as part of a 900-year-old English legend. The original Lady Godiva was an 11th century noblewoman married to Leofric, the powerful Earl of Mercia and Lord of Coventry. As the story goes, Godiva was troubled by the crippling taxes Leofric had levied on the citizens of Coventry. After she repeatedly asked him to lessen the burden, Leofric quipped that he would lower taxes only if she rode naked on horseback through the center of town. Determined to help the public, Godiva stripped off her clothes, climbed on her horse and galloped through the market square with only her long flowing hair to cover herself. Before leaving, she ordered the people of Coventry to remain inside their homes and not peek, but one man, named Tom, couldn’t resist opening his window to get an eyeful. Upon doing so, this “Peeping Tom” was struck blind. After finishing her naked ride, Godiva confronted her husband and demanded that he hold up his end of the bargain. True to his word, Leofric reduced the people’s debts."
