A Transistor Museum Interview with Jack Haenichen

The Development of the 2N2222 – The Most Successful and Widely Used Transistor Ever Developed.

 

Oral History – Jack Haenichen

They were the first silicon transistors, and they made a startling announcement at one of the IEEE meetings (I can’t remember what year it was), but everybody was giving papers about germanium transistors, and the “TI guy” got up and started talking about silicon transistors and he had this bag full of them and he just threw out to the audience – it was a really good publicity stunt.  (Editor’s note: This event occurred in 1954).

 

Anyway, I got there in late 1959, and there was already a big “buzz” in the industry about silicon.  Motorola had also hired a man named Harry Knowles from Bell Labs, and they had just hired a guy from General Electric named Al Phillips – he was working at GE (GE, RCA, Sylvania and some of these other companies had fledgling semiconductor operations as well) and they hired him away from General Electric.  He got there about the same time as I did and he was going to be my boss.

 

 

3) How was the Motorola Semiconductor operation organized at this time?

 

Keep in mind that this was very small.  They had this little research building on 56th St. and they had just built a building on McDowell Rd to manufacture germanium power transistors.  And one of the reasons they were making power transistors was that initially the idea about Motorola Semiconductor Division was to supply parts to other Motorola Divisions.

At that time Motorola had several other divisions – one was called Automotive, another was Military/Government Electronics; they had a Consumer Products Division that made televisions, but their biggest and most important division was their Communications Division, which made two-way radios for entities like police and taxi.  They were, and I believe still are, the world leader in that business. 

 

Dan Noble had been hired by Motorola years prior; he was a professor at a college back east, I believe in Connecticut, in electronics.  He invented, among other things, the squelch circuit, for radio.  He came in and spear-headed that whole Communications Division operation, and got them to a world leadership position.  They were making equipment with vacuum tubes at that time, and of course they wanted to switch to solid state devices – so, that was the genesis of the Semiconductor Division – to supply parts to other divisions of Motorola.  As time progressed, the Semiconductor Operation became almost as large as the Communications Division, and we became suppliers to companies worldwide, including government entities.

 

 

4) Where had you been before Motorola?

 

That was my first job.  I worked briefly at Bell Labs in Murray Hill NJ, so I had a great interest in semiconductors.  In school, I had studied semiconductors and microwaves.
