What sparked Walter Cruttenden's initial interest in investment banking?

Walter Cruttenden's interest in investment banking was sparked by his father's business activities. His father was backing a company called Wham O Manufacturing, which produced popular recreational products like frisbees, hula hoops, and water slides. Seeing these products being brought home, young Walter became curious about his father's profession and directly asked him, "Hey dad, what is it you do? I'm really interested." This curiosity led to his father introducing him to the concept of investment banking, which apparently became influential in Walter's later career path as an entrepreneur and investor.
