Hans Adolf Pestalozzi (February 7, 1929 – July 14, 2004) was a Swiss social critic of late 20th century capitalism, which eventually led to his becoming a bestselling author (Nach uns die Zukunft, Auf die Bäume ihr Affen).
In the 1960s he also built up the Gottlieb Duttweiler Institut, a think tank named after the Migros founder (who had died in 1962).
Rather than looking for a new job, he became a freelance writer and self-proclaimed "autonomous agitator" who sided with the fledgling European youth, peace and ecological movements.
He preached "positive subversion" and, in a Kantian manner, tried to convince people that using their own intelligence was the right thing to do.
Hans A. Pestalozzi died a recluse by suicide in his home near Wattwil, Canton of St. Gallen.
