As a newly minted scientist, Randy Schekman was warned that he was wasting his time.
When he applied for his first research grant, he recalled, "they kind of laughed at my proposal."
But Schekman, who was born in St. Paul, really wanted to find out how yeast cells work. So he stuck with it.
On Monday, he won the 2013 Nobel Prize in Medicine.
"My first reaction was, 'Oh my God,' " said Schekman, 64, now a professor at the University of California, Berkeley. "Then I went speechless."
He shares the prize with two other scientists, James Rothman of Yale University and Thomas Südhof of Stanford University, for discoveries that have led to new ways to produce insulin, vaccines and other medical breakthroughs.
Schekman, who lived in the Twin Cities until he was about 10, was jet lagged from a trip to Germany (to pick up another award) when he was awakened at 1:30 a.m. Monday by the phone call from Nobel headquarters in Sweden.
His wife, Nancy Walls, shouted "This is it! This is it!" he said at a news conference a few hours later in Berkeley. "I picked up the phone, I was trembling." Then he heard "a comforting voice with a Swedish accent" offering congratulations.
