First Hispanic Nominee - And Jewish Too

As Fark notes:

Many people calling Sonia Sotomayor first Hispanic Supreme Court Justice. These people are wrong: The estimable Justice Benjamin Cardozo, nominated by Hoover in 1932, had that honor. Please make a note of it.

As sourced:

Some of Cardozo's ancestors were Portuguese Jews who immigrated to Britain's North American colonies in the 1740s and 1750s from Portugal via the Netherlands and England. The surname Cardozo (Cardoso) is of Portuguese origin.

And he was Jewish, too.
