As the Style Sheet says:

Avoid vanity: do not name the sequence after yourself (or your family members, your friends, etc.).

I've collected here some examples and non-examples for my own purposes. Below, I use "discoverer" loosely; sometimes the sequence was known or 'obvious', but the named mathematician discovered properties which made it interesting.

Of course, the discoverer is often not unique; many of these had been discovered before, or were otherwise misnamed. In some cases the person was wrongly attributed the discovery, but the name stuck. See Wikipedia's List of misnamed theorems for some examples.

## Non-examples

### Named after discoverer

This is a list of sequences named after a discoverer by the mathematical community. In several cases the particular name has been codified by the OEIS. Note that the concept of "discovery" in mathematics is very wide, and this list follows this expansive view rather than attempting to determine which of various candidates is most worthy of being considered "discoverer".
