Bill Cooper spent two decades building what was once a failing thrift into the Minnesota banking power TCF Financial Corp.
Then, just into Cooper's brief Florida retirement, the brutal downturn that started in 2007 threatened both the company and his own fortune. For Cooper, there was only one way to respond: get back to work.
"I have a real emotional attachment to this company. It's like one of my children," Cooper said when he returned to the company in 2008. "I also have a real economic attachment, which may be a stronger attachment."
Cooper, 73, died Tuesday night at a Twin Cities hospice after being ill for several years with a blood cancer. He remained TCF's chairman until his death and an animating figure in Minnesota's business and political communities, and an activist for school choice.
Banking colleagues credited Cooper's original thinking as a big factor in TCF's success.
"Bill Cooper was not a me-too banker," said Craig Dahl, who succeeded Cooper as TCF's chief executive in 2015.
"That set us apart in the early days, thanks to his innovations," Dahl said. "He started seven-day-a-week banking, supermarket banking in this market and giving every customer a debit card. He was a leader and a pioneer."
Cooper was always outspoken and often controversial. His colleagues recalled him as a taskmaster who was by turns stern, witty and kind, with a heart for disadvantaged kids.
