I see. Commercial success is your only measure.

Fessenden was a commercial success. In 1915 he perfected his device to
measure ocean depths, the "fathometer" which gave him finicial security
for the rest of his life. In 1928 he won a settlement for $500,000 (a
LOT of money in 1928) for his patent lawsuits.

I did not know that! Thanks, JJ!

I guess that means Len was wrong - *again*.

So RAF was not only a genius but also a commercial success with at least some
of his inventions.

Sunuvagun!
