Didn't David Sarnoff also steal electronic television design from
Philo Farnsworth and claim it as RCA's invention? 

I think from memory Farnsworth had  "image dissector" camera tube
some years before Zworykin came up with the Iconoscope.

But you never hear of the name Farnsworth, apart from the cynical
naming of the mad scientist in Futurama.

Money rewrites history.

 The feud and patent litigation between Armstong and RCA 
 is very well documented. Armstrong had problems with patents 
 other than FM such as the super regenerator. There were 
 good reasons for changing from the 50-54 mhz band to the 
 upper one, for instance there are about four times the 
 number of channels available. Also 50 mhz has problems with 
 long distance co-channel interferrence. The problems are not 
 as simple as a personal vendetta although that certainly 
 existed. Curiously Armstrong and Sarnoff were good friends 
 before their egos got in the way. Armstrong's wife persisted 
 in the patent fight after his suicide and eventually 
 prevailed. She had been Sarnoff's personal secretary before 
 marying Armstrong.
 The reason that Westinghouse was invited to become a 
 part of RCA after its original formation was that they held 
 important patents assigned to them by Armstrong.
