Michael Bloomberg’s name is closely associated with philanthropy, but his extraordinary giving to Johns Hopkins University began with something remarkably small: a $5 donation. Decades later, the US billionaire, entrepreneur and former New York City mayor has contributed more than $1.5 billion to his alma mater, helping reshape financial aid, medical education, public health research and the university’s broader academic mission.While MacKenzie Scott has attracted global attention for her large-scale philanthropic giving, Bloomberg’s decades-long relationship with Johns Hopkins offers another striking example of how billionaire philanthropy can transform an educational institution.Bloomberg graduated from Johns Hopkins in 1964 with a bachelor’s degree in engineering. The following year, he made his first $5 donation to the university. That modest contribution eventually grew into what the university describes as more than $1.5 billion in total giving.ALSO READ: Jeff Bezos’ ex-wife MacKenzie Scott, who sold half of her Amazon stake, helped erase $40 billion in medical debt with $100 million in donationsFrom a $5 gift to more than $1.5 billionBloomberg’s relationship with Johns Hopkins has lasted for more than six decades.
