yes Marconi... http://en.wikipedia.org/wiki/Guglielmo_Marconi

...who apparently died exactly one century after the Analytical Engine
was designed...

It appears the earliest telegraph experiments happened somewhere around
this time-frame. I don't know how widely-known they were at the time though.

Ooo, look:
http://www.fourmilab.ch/babbage/contents.html
I just read the report of the committee advising against building the
Analytical Engine. It always seems like such a short-signed decision.
Like they had no idea what the possibilities of the machine were.
However, on reading the report (with all its amusing language), it
appears that the /actual/ reasons where:
1. The designs are unfinished.
2. It is unknown whether the design would actually work properly.
3. It is unknown what the machine would cost to build.
4. It is unknown how quickly the machine would wear out.
These are actually pretty valid objections, really...

Heheheh. Victorian English. Dear me, this stuff is amusing.
"Such works could not be carried on without great expenditure. The
fluctuations in the demand and supply of skilled labour were
considerable. The railroad mania withdrew from other pursuits the most
intellectual and skilful draftsmen. One who had for some years been my
chief assistant was tempted by an offer so advantageous that in justice
to his own family he could scarcely have declined it."
Damn. I could have just written "this required skilled labour, which the
railroads soaked up". Heh.
