thanks for the references! Certainly there was allot of interesting
research at the beginning of radio, and some characters more
controversial than Tesla, like Stubbelfield. Today things are quite
different, allot of old stuff keeps getting churned up in radio, and
greater emphasis is on information theory. Also Maxwell's equations
are difficult to apply to all situations leading to extensive use of
finite element theory where antenna systems are developed in computer
simulations. Add to all this is the fat that universities are driven
by paper publication and so there is allot of repeated stuff and only
small advances here and there.
For instance there was all that commotion over wireless power by
magnetic induction, and was presented as a great new idea, along with
a nice colourful simulation; this has been done so many times before -
nothing new, but it was branded a new technology an advancement of the
modern age. Meanwhile there are half a dozen websites were people have
built such a system (I had a few years ago) and Tesla said it was no
good, all this without the nice colourful simulation.
I think the Marconies, Teslas, Edisons and de Forests have long gone;
people are just plain scared to pick-up a soldering iron, but rather
sit in front of their PCs considering the "possibilities."

Sorry to go on.

   Some people (and authors too) seem to view Tesla's work as if it
were conducted in a vacuum and that he was working in a completely
new field.  They don't seem to realize that the latter part of the
19th century was a time of very vigorous study, experiment, and
exploitation of electricity and its applications and that he was but
one (a preminent one to be sure) of many men working the field.  This
started in the days of Ampere, Faraday, Henry, Morse and continues
unabated today.  There were plenty of books published during the
period which give a pretty good idea of the technical state of the
world in which Tesla lived but most are hard to find today.  I'm
fortunate enough to have acquired a few early references but others
may not have the interest and want to invest the effort to access
some of them.  I believe any real student of Tesla history, at least
in relation to wireless and radio, would benefit from studying the
following references which are still available:

More or less current references on early days of radio and wireless:

edited by George Shiers

Arno Press (NY Times) 1977

Covers work by Lummis/Ward and Stubbelfield on from conduction and induction

systems through "Hertzian" systems.  Good and thorough discussion of
the subject,

giving a good picture of the work before Tesla and the "state of the
art" of the late 19th

century and later.

The Origins of Radio"

Hugh G. Aitken [professor of economics at Amherst and student of technology]

Wiley Interscience, J.Wiley, 1976

Discusses the same general subject with emphasis on the requirements for tuning

and of the various researchers who recognized it.

Technology and American Radio 1900-1932"

Excellent presentation on the subject.  He places Tesla in historical
perspective and

treats him realistically and very sympathetically.
