Jerry is not a leader and can only be counted on for knee jerk business responses. The reality is TI shamelessly took ADI's business plan (Linear + DSP) and executed on it while Jerry idled the time away. It was under Jerry's watch that TI transformed from a DRAM manufacturer to an analog DSP company and screamed past ADI.
Also, a great leader has nurtures a deep bench of management talent to follow. Who can lead ADI past the future competition?
computing developments. (the ASC)
I never was sure why.
Perhaps for seismic data processing,
or for submarine tracking.
TI had a Wallace-tree multiplier in the
original TTL databook (the huge yellow book).
I was puzzled as to who would want a 2X4 bit
multiplier building block, but I realized
a summarine has lots of electrical
capacity and an entire ocean for heat
Thus using those WallaceTree ICs to build
FastFourierTransform boxes, to search for
enemy subs, perhaps with phased-arrays
of transducers for directional searches,
There is a reasonable report at
which discusses his 1952 contribution. The
RRE/DERA journals show him predating the
Bell Labs team, but they are not publicly
A lame rebuttal, I know.....
Either way, his work pre-dates Kilby which
was the original thread!
Interesting. Could you adduce material showing that Mr. Dummer conceptualized the Si (or for that matter any other semiconductor) transistor? I would be interested in seeing it. I have never heard of anyone predating the Bell Labs team in this field in any way.
First public disclosure is usually considered
the source of invention as far as patent law
is concerned. An extension of that law is the
right of patent infringement protection which
is granted if non-disclosed official
documentation can be offered in defense.
Our friend Dummer worked on the idea of a
silicon transistor during the war years and
can be evidenced by the British Ministry of
Defenses archives; his original intent was
to replace the valves used in bombers.
Unfortunately he was not allowed to make a
public disclosure during war time for obvious
reasons. TECHNICALLY, you are correct
Shockley and co made the first public
disclosure and are considered the inventors,
however, together with other war time British
inventors such as Frank Whittle (the guy who
invented the jet engine) a lot of the credit
has been lost to those who commercialized the
That old adage applies here - history is
written by the victor!
Rubbish! (as they say in the U.K.).
Just because you THINK of something doesn't make you an inventor! Did Jules Verne 'invent' rockets or did Wernher B & Co??
On the other hand, the TI IC 'invention' was really an obvious and trivial extension of the concept of semiconductors. The real semiconductor heroes are and will always remain real physicists Bardeen, Brattain & Shockley, not soem twit EE (like me!).
