7. The Beloved Mother Teresa
Mother Teresa is known for being a champion of the poor as she worked tirelessly to help disenfranchised people in Kolkata, India. Her devotion to this cause lasted for nearly 50 years, and Mother Teresa earned the Nobel Peace Prize in 1979. This Catholic nun had a major heart attack and received a pacemaker in 1989. She passed away in 1997, and was canonized as a saint in 2016.
