Excuse me, MAC Pherson strut spring design assembly.
Designed by an engineer who quit GM and went to work for Ford of England. They patented the design and gave him a good retirement.
Colin Chapman took the same design and patented it for the rear applications(Ford missed that one) and that's where the Chapman strut came from
Earl S. MacPherson(so close, my dad was Earl F. MacPherson, ah well, mebbe next lifetime)
