Businesses that thrived during recessions?

Working on a little list for inspiration. Do you know stories of companies that started, or thrived, during economic down times?

Here is the list Ive found so far. Looking for more please! You can find a history of U.S. recessions here to help sort things out. Here’s a partial list of world economic crises. If you have better lists, leave a comment.

Toro lawnmowers. Formed late in WW I right before the post war recession.
Trader Joes. Formed in 1957, during the recession of 1957 and 1958.
Target. It’s on the borderline. Wikipedia claims Target formed, seeded by the Dayton department store, in 1962. The 1960/61 recession officially ended about a year before.
3M. Started in 1902, and despite major setbacks, survived the panic of 1907, eventually gaining new investors around 1910.
Google. This is also a technicality. Google first got funding in 1998, before the 2001-2003 dot com bubble burst. And had it’s IPO in 2004. But belongs on the list for having it’s major growth at the same time period the rest of the tech sector fell apart.
