Science history scavenger hunt

[petrea_mitchell]

Reading the newsletters for this year's Eastercon (the UK national sf convention) as they get posted, I came across this:

John Holden’s display of arc lamps will be set up in the Aviator conference centre, outside the Armstrong room.

Jules Duboscq was a world class Parisian scientific instrument maker.

He made at least 509 carbon arc lamps between 1840 to 1885 and these were bought by the most renowned scientists around the world. Then many moved into national science museum collections.

The Arc Lamp man has found one percent so far.

Can you make it two percent by taking part in this hunt to find another half dozen?

How to do it:

1) Log onto a national science museum, world class University or science research site from around the world.

2) Find the search collections part of the site. Filter for objects.

3) Search “Duboscq”

4) If you find one then send the picture and link to: johnholden07450@gmail.com

Happy hunting and can we find where another six lamps live?

By not precisely following these steps, I was able to find one at the Smithsonian, one at the Swedish National Museum of Science and Technology, and multiple ones at Harvard and the Rijksmuseum Boerhaave. I doubt all of those are new to him, but I sent them all in just in case. Some of you can probably do a lot better than me though (delosharriman, I'm looking at you).

You made me stop and think : do I have one?

The answer is, no I do not. I do have some quite exotic light sources (mostly courtesy of an older gentleman who used to run a test lab, and gave away a bunch of his stuff to members of the Dallas Makerspace), including a deuterium lamp, but they're all from the 20th Century.
