Data of birth
In the old age M Waldemar didn't always tell his correct age. We have however two good sources about his birth date. One of these is the interview with him from February 1987 (listen below at 41:02 for the interview with M Negoativo):
«I have 72 [probably 71] on my back. I will now be 72 years old on 22nd February.»
In the other source: Mestre Waldemar (Waldemar da Paixão), born in Salvador on 22nd February 1916.

Place of birth
[..] capoeira, that [M Waldemar] brought from Ilha de Maré to show that it's not only the city of Salvador that produces good people in the fight and in Angola.

Other mestres with the same name
PS There existed also two other mestres named Waldemar:
Waldemar Santana, who also practised capoeira, but not as folklore (he was a jiu-jitsu and vale-tudo fighter), and was born in Salvador on 29th October 1929.
Waldemar dos Santos, student of M Bimba, born in Salvador in 1935, 8th December(?), who had his academy in São Paulo.
