Mies van der Rohe is often credited with flipping the concept upside down by saying: “God is in the Details”. Regardless, it means that if you do not pay attention… Read more »

Sergio Marchionne, An Appreciation of a Leader

I have always had an odd fascination with Chrysler. The whole story is too long to get into, but it relates to my Mother first seeing value in Chrysler stock and timing the ups and downs like Paganini on a violin, and my days at Chrysler’s Highland Parks Tech Center working with Chrysler engineers on… Read more »

Happy Anniversary IMO, a Sterling Example of International Cooperation

I joined the industry in 1981 and, before that, remember playing with the tarballs on the Dutch Northsea beaches.

An Ode to Freestanding Masts

A week or so ago, for a minute, Lenny Pucci and I were thinking about jointly owning a sailboat. That immediately raised the next question: Well, what kind of sailboat?
