I've googled 'famous aerialists' and 'famous Roma'. What I'm trying to determine is that if Dick's ambition at this stage is to become one of the best acrobats ever--better than the Flying Wallendas, etc... to whose skills might he aspire? It's a bonus if the performer is Rom/Sinti etc. (His father is Roma--but http://www.imninalu.net/famousGypsies.htm and http://en.wikipedia.org/wiki/List_of_Roma_people didn't turn up any aerialists that fit the bill. The first one mentioned that Yul Brynner worked on a trapeze... but somehow 'to be as good a flyer as Yul Brynner' doesn't sound like much of an accomplishment.)
I'm thinking of performers who were probably well-known in professional circles between the 60s and the 80s--i.e. people his parents might have seen perform live.
