Re: ALGOL, PASCAL, MODULA 2, ADA
Pascal still lives in Delphi and Free Pascal.
Modula2 is fairly dead (while there is a GNU M2, it isn't the most active). It was used quite a bit in the mid nineties in medical and other.
Wirthian influences are heavily felt in Java (listed in the credits of the VM IIRC), and of course C# is a hybrid of Java with Delphi directly.
