Is it legally fine to name a project or a library with a famous person name?
<p>I wonder if there are any legal reasons for that to be not ok?</p>

<p>There are many precedents, e.g. <code>Sinatra</code>, <code>Kafka</code>, <code>Shakespeare</code>, <code>Django</code> etc , so are there any limitations ? (living people etc)</p>

<p>If you have as much money as Apple, and the famous person is Carl Sagan, then you change the name of your internal project instead of risking a law suit. The difference is probably that Sagan is alive and can sue you, while that is no problem with Kafka, Django etc. </p>

<p>Dead or alive is not the real distinction; don't try to to call your project "Disney". The question is whether there is someone who is going to sue you for it. </p>
