No. For that matter, he didn't really have a last name. His name was Pythagoras. If anyone wanted to make sure that he didn't get confused with some other Pythagoras, they'd say something like "Pythagoras of Samos" (except, of course, that they'd say it in Greek: Î?υθαγόÏας ὠΣάμιος).
The reason we have last names, middle names, etc. now is to avoid any confusion of this sort. Pointing up the need is the fact that there actually was another (semi-) famous Pythagoras living in Samos who was a sculptor and, to make matters worse, according to Pliny the Elder (see, there's another one we need to add a distinctive to; the modern system is looking smarter and smarter) he apparently looked a lot like the philospher/mathematician.

Pythagoras didn't have a middle name. Names and titles through history have evolved into many forms. Pythagoras of Samos tells up his name and where he was from--like Jesus of Nazareth. Your name is usually composed of a first name, often a second, and a family surname. The Chinese put the surname first--Mao Tse-Tung's family name was Mao. Some people use only one name like Cher. Some people use ridiculously long names that spell out all their family associations, titles, religious affiliations, you name it.
He was always reffered to as Pythagoras of Samos.
