The UKs Daily Mail has a report on Matt Loughrey who has spent the last four-and-a-half years working on a technology to redefine and color portraits of well-known historical figures. The story shares several of Loughrey's creations, starting with Houdini! It's a truly remarkable image.
(The caption dates this image as 1912, but it is actually a 1914 shot.)
You can see more of Loughrey's work on his Instagram. Below are a few more glimpses of Houdini in color.
