Erdös Number

Being married to a Hungarian, I am constantly being reminded of the correct pronunciation of Erdös.

For the longest time I believed my Erdös number to be five. However, MathSciNet has a nifty Collaboration Distance Search , and it turns out that it's four (or perhaps less - highly doubtful), via any of these paths:

Erdös -> Deheuvels -> Shorack -> Le -> Gustafson

Erdös -> Mullin -> Lawless -> Dean -> Gustafson

Erdös -> Babu -> Ghosh -> (Srinivasan or Carroll) -> Gustafson
