 Jackie Robinson   rightfully celebrated for showing enormous grace under pressure while breaking baseball's color line  refused to stand for the National Anthem after  his  playing days.
Jackie Robinson as a Brooklyn Dodger.
As  he  described in  his  1972 autobiography   Robinson -- like contemporary NFL players --  was protesting against institutional racism.  He  was expressing  his  feelings of alienation from America's system of racial apartheid.
 Robinson 's pugnacious brand of civil rights activism set the stage for succeeding generations of black athletes. Eleven-time NBA champion Bill Russell emerged as one of the most outspoken civil rights advocates of the 1960s  at a time when the city he played in  Boston  represented one of the most racially segregated cities in the North.
Above all  black American athletes are citizens  fathers  brothers  husbands and sons who have a right and responsibility to continue a long struggle for dignity exemplified by Jackie Robinson  Bill Russell and many others.

Although  raised a strict Catholic  Bettencourt Meyers  married the grandson of a rabbi killed in Aushwitz â all the more notable given that L'Oreal's founder  EugÃ¨ne Schueller  was a known Nazi sympathizer .
 Bettencourt Meyers  is arguably best known for bringing legal action against  her  mother  after the elder Bettencourt began giving away millions in assets and insurance to society photographer FranÃ§ois-Marie Banier  with whom she'd struck up an unusual friendship.  Bettencourt Meyers  accused Banier of preying on  her  mother's onsetting dementia. When  Bettencourt Meyers  sued   her  mother responded by calling  her  daughter âune emmerdeuseâ (a pain in the ass)  according to Vanity Fair .
The case was ultimately decided in  Bettencourt Meyers'  favor  and  she  and  her  two sons were named guardians of Lilianeâs interests in 2011.
