Why do they callmadame cj walker madame?

Madam C. J. Walker, who was born Sarah Breedlove, adopted the title "Madam" after marrying her third husband, Charles Joseph Walker. There are several reasons for this. 1) Many businesswomen during the late 1800s and early 1900s adopted the title to show they were in business at a time when professional and business opportunities were very limited for women. Women who were seamstresses, caterers, opera singers, actresses, boarding house proprietors -- and yes, some women who ran bordellos -- used the title. But that latter kind of illegal business, of course, had nothing to do with Madam Walker's hair care business. 2) American women who were pioneers in the cosmetics and hair care industry like Madam Walker, Helena Rubinstein, and Elizabeth Arden used the title as a way to identify with the French title "Madame" (the word for "Mrs.) and with Paris, which then was the center of fashion and glamour. 3) In Madam Walker's case, she used her husband's initials to prevent people from calling her by her first name and disrespecting her at a time when many black women were called derogatory names and not addressed as "Miss" or "Mrs" by some whites who wanted to prevent them from succeeding.
