What started as a deep dive on Nikolaus Otto ended as a second installment of inventors that are famous for just a single invention.

 

Why did this happen? Well, because Nikolaus Otto didn't do a whole lot other than the four stroke engine, but that sure was a great invention!!

 

In addition to Otto, we discuss others like Laszlo Biro, Samuel Morse, John Walker (not to be confused with Johnnie Walker) and more. They may have only invented one thing, but each one was a real hit.
