Karl Mueller: ‘I realised I had matured when I started giving away my best ideas’

I grew up the second of four children in the rather small city of Tonawanda, New York, which is about halfway between Buffalo and Niagara Falls on the beautiful Niagara River.

We spent a lot of time running around outside, like many kids in the 1960s and 1970s, and played a lot of street hockey. I also explored tons down at the Niagara River – a lot of swimming. My family was big into fishing, so we spent a significant amount of time on the water.
