Who would be some active or can even be very recently retired/deceased mobsters who you think have seen the most things throughout their criminal careers, not necessarily the most successful or richest just ones who've been around for a lot. A few that come to mind

Albert gallo...to be around during both Colombo wars with his brothers and then switch families to still be active today.

Mario gigante...retired but I'm sure he has seen and done so much.

This is just a start I'm sure there are tons more.

I don't usually engage in hypotheticals because there is no definitive answer but I can assume older mafiosi such as Joe Arcuri and Sonny Franzese must have witnessed a lot; if you discount the fact most of these guys, like Franzese, spend a large percentage of their life behind bars.

Sonny franzese comes to mind most defiantly !! He is 97 years old Ming!! Chinky Facchiano (Albert) from the genovese's who died at 101 years old in prison ... Still active to the end. Can I mention joe bonanno ... He died at 97 to in 2002 but he retired in the 70's I would say... So he may not count. But he outlived every original boss since the 5 families and the commission was formed in 1931. Benny eggs mangano is 93 years old... Still active. I can't think of any others lol

The Chin and Neal IMO

Both were deeply involved in some huge power plays and regime changes

I reckon john gotti seen more than most also , his reign was very eventful

im not sure I would consider gottis reign eventful. although my distaste for this individual adds to my judgement. I would have to say joe bonano, from marananzano to Luciano, to gotti, he saw them all.

Bobby mannA and sonny franzese

No Nose did his first hits for the Outfit over 60 years ago. He was around when Ricca and Accardo were in charge before Mooney became the boss

any low level mobster thru living thru either prohibition or the 50s-70s.

I've seen the most. no one has seen as much as I have.

Benny Eggs, Matty, Chin, Mario, Jimmy Alo, Gerry Catena, Al Gallo, Punchy, Sonny Franzese, the list goes on. Impossible to pick ten guys, let alone one.

Two recently deceased ones - Matty Ianniello and Tino Fiumara.

Accardo was a gunman for Al Capone and lasted through the 1980's when he retired. He was at or near the top for 40 years.

I AGREE Tony ACCARDO Saw the most he was a body guard and Hitman in 1920s Hitman and Capo In the 1930s Under Boss then Boss in the 1940s And 1950s Then a Hidden Boss And Adviser From the Late 1950s till 1992 What a Guy

The old FIVE strikes from behind reginald .

the street mafioso that made it through the the castellammarese war. or that of the chicago mobsters during that same era. i'd actually say the chicago mobsters they were much more violent than the new york ones. people like tony accardo and sam giancana probably saw alot. anyone who came up under a violent boss would of had seen alot if not on his good side. maybe carmine persico or the gallo brothers

I Agree Tony Accardo saw the Most 1920s - 1992

Carmine Persico, Sonny Fran, Benny Eggs,Kid Blast. How about Matthew Madonna? any one who is still alive that were active in the "Golden Years" have seen alot. As far as dead or alive have to mention guys who were active during prohibition and were still alive in 70s,80s, and 90s. Hell Bonnano lived until 2002!!

Stephen Grammauta is 98...involved with the gambinos since the 30's!

And the feds chased them with a vengeance, literally, till the day they died

He may not be active anymore, but Little Larry Dentico has seen alot. He worked for Vito Genovese in the 50's and I believe may be an advisor of sorts for the current administration?

great pick. since that guy apparently never did seriously time in prison and is still alive, hes a very good choice in my opinion!
Imagine if this guy would publish his memoires..
