Lol, I thought you were still going on about vacuum cleaners.

 

It is indeed Ernest Henry. The Swiss engineer who built the first ever 4 valve (per cylinder) twin OHC engine............as long ago as 1912! Which begs the question why were we still wasting our time with side valve engines on regular cars 50 or 60 years later??

[baldie]

Ernest Henry invented the twin cam engine?

[Vista]

Ernest Henry invented the twin cam engine?

No, but he was the first to combine double overhead cams with 4 valves per cylinder.
