| Description |
The book Feynman's Tips on Physics, Addison-Wesley, 2006, uses this photo on the cover, and states that the photographer is unknown, and that the photo is from ca 1962. I'm sure AW (which is continuing to make money on Feynman's stuff) would love nothing better than to be able to show the photo was copyrighted, and I'm sure they did a routine copyright search on the photo before using it on the cover. Works published in the US before 1964 had to have their copyrights renewed after 28 years, or they expired, and since I assume AW did a copyright search, it sounds like the photo's copyright was not renewed. |
