Concord, Mass. — Darkness has fallen over the outskirts of historic Concord and the office workers at Kazmaier Associates are heading home. The boss, however, still has several more items to tend to, including a lengthy interview.
Dick Kazmaier, the former Princeton University star, may have quit running with a football after he won the Heisman Trophy in 1951, but in just about every other way he seems to be going harder than ever.
A successful entrepreneur, he oversees his own business from its semi-rural headquarters west of Boston. The company, a consulting firm involved primarily with sports marketing and management, is on the move. Within the next few days, the concern will sign a deal to handle the New England franchises for D'Lites, a fast-food chain specializing in ''lite'' fare.
In keeping with the Kazmaier style, though, there is nothing pretentious about this budding enterprise. Its new, handsomely styled building carries nothing more than a street address sign. ''Dick is a very low-key guy,'' an assistant explains.
Kazmaier is, however, justifiably proud of having won the Heisman Trophy. But he places the honor in context. ''My selection was representative of Princeton's excellence and accomplishments at the time. That's not what it is in the eyes of the public, but that's how I view it.''
The Ivy League school received as much exposure then as any team in the country, except for Notre Dame. The Tigers were an undefeated, sixth-ranked team in '51, when Kazmaier was the nation's total offense leader and most accurate passer.
But his fondest recollections today are not of specific plays or games. ''I could tell you about some plays, but the most important things were the experience, the opportunity, the people,'' he says.
His college experience was so satisfying, in fact, that he had no desire to enter pro football - even at the urging of George Halas, revered coach of the Chicago Bears. Instead he enrolled at Harvard Business School, married after his first year, then joined the Navy upon completing his MBA degree. Six years passed before he resurfaced as an everyday citizen.
''That's a long time to be desensitized and cooled off (from the Heisman attention),'' he says of his ability to escape post-award clamor.
He preferred it that way, too. He basically divorced himself from the honor, giving the trophy to his father, who gave it to Princeton.
''Until 1971 I didn't have any of my memorabilia with me; I didn't want it,'' he explains. ''That was a phase of my life that had concluded. I wasn't prepared to deal with the next phase, carrying the Heisman Trophy under my arm or wearing an All-America sweater on my back.''
In becoming a hardworking businessman and the father of six daughters, he basically put football behind him. So much so, he says, that a certain inertia set in, preventing him from accepting his football past after two decades of stiff-arming it aside.His wife, however, encouraged a change.
''It was her desire, and I thought it was good one with a whole bunch of teen-age girls, to have some things around the house that might show the history of their parents.''
Accordingly, he now has his own Heisman Trophy, but not the one given to Princeton. When Kazmaier attended O. J. Simpson's Heisman press conference in 1968, he learned that beginning with Simpson, winners would receive two trophies , one for their schools and another for their personal use. So he requested a second copy of the famous statuette.
Since then he has become more openly involved in football and today is president of the National Football Foundation and Hall of Fame. He attends a handful of games each year, and on New Year's Day - in the best tradition of American football fans - he watches bowl games on two TVs simultaneously.
