    I remember it being claimed in the 1940s that the 'Miller Integrator' had in
    fact been invented by Blumlein, some papers referring to the circuit as a
    'Blumlein Integrator'.
    Has history elucidated who is rightfully regarded as the inventor ?

  2. I confess that I have not researched that particular bit of history, but
    is it possible that because the integrator made use of the "Miller
    effect" (discovered by Miller), Blumlein called his integrator a "Miller
    effect integrator" which later become shortened?

    I can't think of anything Blumlein invented which he named after himself
    at the time. The attributions seem to have been applied by others at a
    later date. Herbert Holman and Henry Clark were the 'inventors' of
    many of Blumlein's electromechanical devices; but it wasn't until
    Blumlein's superior theoretical knowledge was brought to bear on them
    that they achieved their full performance and were put into practical
    use.

    I expect the answer will be found in his notebooks if someone wants to
    take the trouble to look through them.
     
  3. There was a thread here a year or so ago.

    Blumlein's peers at the time did start to call
    it the Blumlein Integrator but Blumlein himself
    apparently preferred to give the nod to Miller.
     
  4. <http://www.doramusic.com> has a good read.
     
  5. If memory serves, Scroggie was quite the defender of Blumlein who, IIRC,
    also came up with the stereo LP system and many other inventions.

    That's easy. "Miller integrator" rolls smoothly off the tongue - who
    would want to use a "Blumlein integrator"? ;-)

    Cheers!

    Surprised to find he couldn't read and write when aged 13.
    Interesting to see that documentary.

    The account of the crash was interesting, especially
    the two people who gave up their seats at the last
    moment and the chap who nipped off for a cup of tea
    and so missed the takeoff. One of them was Bernard
    Lovell. If he had died the Jodrell Bank telescope
    might not have been built.

    The IEE press has published The Life and Times of A D Blumlein by Russel
    Burns as part of their history of technology series, and a substantial
    portion of the text is readable in PDF format on Google Books. This is a
    ridiculously overpriced book otherwise.
     
  11. No? Wikipedia claims that at age 7 he wrote an invoice to his mother 'for
    repairing the doorbell, signed "Alan Blumlein, Electrical Engineer".'

    If anybody has access to "Wireless World" from the early 90's there
    was a long series on famous folk (Maxwell, Ampere, etc, etc) and there
    was one on Blumlein. I recall some discussion on the integrator, but
    not any more detail.

    Who should I believe?. The Wiki or the Alexander Biog' version of events?.

    http://www.doramusic.com/Who Was Blumlein.htm (4th paragraph down)

    Alexander's site comes across as a case study in rampant self publicity and
    egocentricity and I also cannot imagine Blumlein's wealthy parents allowing
    illiteracy in the family. So choice made ... I'll go with the Wiki :)

    (I've a feeling 'Steiner/Waldorf' schooling has somehow seeped into the mix
    but we are not told)
