My Erdős number

A person's Erdős number is 1 if they have coauthored a paper with Erdős, 2 if they have coauthored a paper with someone whose Erdős number is 1, and so forth.

I list below my Erdős number, as well as my number for some other famous scientists.

Albert Einstein (Nobel Prize 1921):

My Einstein number is 4.
(My thesis advisor has an Einstein number of 2, through his thesis advisor.
And counting an unpublished preprint [by other authors] would reduce my number to 3.)

Michael Atiyah (Fields Medal 1966):

My Atiyah number is 4.

Freeman Dyson (Wolf Prize 1981):

My Dyson number is 4.

Niels Bohr (Nobel Prize 1922):

My Bohr number is 3.

(The Collaboration Distance calculator at MathSciNet incorrectly gives my Erdős number as 4.)
