Who is Passepartout? What positions has he held?

Passepartout is Phileas Fogg's valet. He has worked in a variety of different positions, as is evident in the quote below.

I've been an itinerant singer, a circus-rider, when I used to vault like Leotard,and dance on a rope like Blondin. Then I got to be a professor of gymnastics, so as to make better use of my talents; and then I was a sergeant fireman at Paris, and assisted at many a big fire. But I quitted France five years ago, and, wishing to taste the sweets of domestic life, took service as a valet here in England. Finding myself out of place, and hearing that Monsieur Phileas Fogg was the most exact and settled gentleman in the United Kingdom, I have come to monsieur in the hope of living with him a tranquil life, and forgetting even the name of Passepartout."
