Renaissance and Early Modern Occultists

One of the things I try to do is to include historical people as NPCs in my setting. As my campaign is just introducing a supernatural element, I wanted to have some actual alchemists and occultists to provide color and as allies and enemies for the PCs. Honor+Intrigue includes modular systems for adding alchemists, weird science and mad inventors, magical talismans, sorcery, and supernatural creatures to the campaign. Here's a list I created for my campaign. I intentionally ignored anyone before the Renaissance, though they might be useful as the creators of books of knowledge or ancient artifacts. I like to keep the list short enough to be useful. If I were running an ancient, dark age, or medieval campaign, I'd focus on people from those time periods. Similarly if I was running something set in the 18th or 19th century I'd use more of the names from the Enlightenment and Victorian periods. Here's the list I created.

The longer list on Wikipedia includes other eras. One of the things Wikipedia is good at is creating list pages. They can be a great starting place for locating all sorts of resources for campaigns, historical and fictional.
