Death of a staunch advocate for the disabled

While she wasn't really a "safety" hero, Harriet McBryde Johnson was certainly a hero to the disabled.  Confined to a power wheelchair, herself, Ms. Johnson was a tireless and eloquent defender of the rights of severely disabled persons.  Educated as a lawyer, she first gained prominence through essays she published repudiating the philosopher Peter Singer's advocacy of killing disabled infants at birth.  Ms. Johson died earlier this month at age 50.
