Simon Parkin manages to make the rather dense topic of publicity rights both fun and accessible in this fascinating look at who owns Einstein’s face.

In the mid-1980s, the university began to assert control over who could use Einstein’s name and likeness, and at what cost. Potential licensors were told to submit proposals, which would then be assessed by unnamed arbitrators behind closed doors. An Einstein-branded diaper? No. An Einstein-branded calculator? Yes. Anyone who did not follow this process, or defied the university’s decision, could be subject to legal action.
