Even though it wasn't entirely under Daniel Lefever's leadership, the various reincarnations of his businesses spanned quite an acceptable period of time compared to some other respected marques, admittedly some still in business.

Is John Olin considered a failure because the Model 21 didn't add to his company's bottom line and his company ultimately ended up in someone else's hands?
