Sylvia Bloom, a legal secretary who worked at the same firm for nearly seven decades, lived a modest life in Brooklyn, riding the subway to work most days.
But unbeknownst to her friends and family, she was a closet millionaire. The frugal secretary, who died in 2016, quietly amassed a fortune of more than $9 million through a string of savvy investments, according to The New York Times.
In her will, she left $6.24 million to the Henry Street Settlement, a local social services group, along with another $2 million split between Hunter College and a scholarship fund.
Bloom is far from the first person to discreetly cultivate riches while living a life of apparent thrift. Here's a look at some other secret millionaire philanthropists whose company she has joined.
She was a former flight attendant and onetime teacher who seemed to survive on peanut butter and ice cream, spending her twilight years in a crowded row house in West York, Pennsylvania.
But when Schwartz died at 93 in 2013, she left $3.4 million to a local community foundation to help teachers and students, according to the Daily Record.
"To apply her own personal education to create a legacy that lives forever for others," Bryan Tate, the vice president of the foundation, told the newspaper. "What a grand and exciting way to be remembered."
