Relationship with Ray Kroc

The couple lived a comfortable yet modest life, engaging in various philanthropic endeavors. Marilyn supported several local charities, community centers, and healthcare causes. Although much of her work remained out of the media spotlight, she earned quiet respect within her community for her generosity and compassion.

Despite her proximity to such massive success, Marilyn did not take an active role in the corporate side of McDonald’s. Instead, she was more interested in how the company’s success could be used to benefit others. Her personal philosophy aligned with the idea that wealth should be used to uplift communities rather than solely to accumulate personal luxury. She believed that the success of McDonald’s offered opportunities to make a positive difference in people’s lives, particularly in areas such as education and public health.

Marilyn contributed to numerous organizations and charitable events that sought to improve the lives of underprivileged individuals.
