Hi, I'm Dick Lyon. I am a research engineer in Silicon Valley, California.
History bug
I've been bitten by the history bug, so I've researched the history of several topics, and added history sections, comments, or links, to articles, such as these:
Contributions to the Wikipedia
My contributions are mostly related to photography, photometry, and signal processing so far. My contributions on these articles range from very small to total rewrite; see the respective histories.
