(CNN) -- Sidney Frank made millions marketing Jagermeister and other alcohol brands. Three years after his death, he's a big hit with students at the Ivy League college he briefly attended.



Sidney Frank, shown accepting an honorary degree in 2005, gave $100 million to Brown University.



He's a big hit not because of what he sold but because he's given dozens of them what he couldn't afford as a young man: an education at Rhode Island's Brown University.



On Sunday, 49 students from low-income families became the first four-year Sidney E. Frank Scholars to graduate from Brown, owing virtually nothing except gratitude to the late liquor magnate.



"The world of difference that he made for each and every one of us is unbelievable, incredible," one of the Frank Scholars, 22-year-old Shane Reil, said Sunday.



Frank -- who left Brown after one year in the late 1930s because he couldn't afford to stay -- gave the school a $100 million endowment in 2004. He stipulated that the fund's income go exclusively to covering all tuition and expenses for the neediest of Brown's admitted applicants.  Hear graduates say how their dreams came true »



For this year's graduates, tuition and expenses came to a four-year total of about $180,000 each. The median annual income of the recipients' families was $18,984.



The gift was the largest single one ever given to Brown and one of the largest ever given for undergraduate scholarships in the United States, according to the school.



Reil, a history major who is preparing to co-chair a student conference on U.S.-South Korean relations and aspires to work in politics or foreign service, says the scholarship was the stuff of dreams.



He was working up to 40 hours a week during high school so he could pay for clothes and even help with grocery bills. He and his mother were getting by, but the Massachusetts native thought community college or a big state school would be all he could afford.



When his academic achievements put Brown in his sights, he thought he'd have to go into too much debt to go there. But he applied anyway, and Brown invited him to campus to tell him about how much the school would award him.



"I sat in this guy's office ... and he said, '$37,000 for tuition,' " Reil recalled. "I said, "$37,000, that's going to be split over four years, so essentially I'm getting a $10,000 scholarship per year.'



"He said, 'No, no, that's $37,000 for this year, and it will be covered [the rest of the years] too.' "



Reil said he cried in the office and ran to his car, where his mother was waiting.



"She was crying so much, we had to sit in the car for so long because she couldn't drive. It was a great moment," Reil said.



"Having the opportunity to go to a really good school ... I think it took my world from a very small area and physical space and just expanded it in multitudes," he said.



Though other universities give full rides, Frank's gift was a coup for Brown. Like many other schools, Brown used to factor a family's ability to pay when deciding whether to accept students.



Brown no longer does that, and Frank's gift was "integral" in bringing the change, said Jim Miller, Brown's dean of admissions.



The school intends to give 30 to 35 Frank scholarships per year. Most recipients are the first in their families to go to college, Miller said.



That was the case for Eliana Reyes Castro, who was born in the Dominican Republic and came to the United States when she was 6. She said she attended a Massachusetts high school that had regained its accreditation only months before she graduated.



Like Reil, she was one of the Frank Scholars who graduated Sunday. She received a degree in education with a concentration in human development
