Born in Columbus, Ohio, and raised in Northville, Michigan, John majored in economics at Amherst College (Class of 1970), graduating summa cum laude, and received his J.D., magna cum laude, from The Harvard Law School in 1973. Following law school, he did post-graduate research at the University of Cambridge (Trinity College). In late 1974, John began a 37-year career as a commercial litigator with a major law firm in New York City. He retired from the practice of law in 2011 and, shortly thereafter, located just outside of Cambridge, England. In March 2015, however, he was diagnosed with ALS. He returned to the U.S., settling in Old Town Alexandria, Virginia. Feeling short of time, he rushed to finish in 2016 the book on science that he had been working on during his retirement. Confined to a wheelchair by 2018, he wrote his first collection of essays, entitled Wanderings of a Captive Mind. The next set, The Eyes Have It, was written entirely using his eyes.
