If you want to do this a lot, you could add your own method to the 
builtin Range class:

  class Range
    def random
      self.begin + rand(self.end - self.begin + 1)
    end
  end

Then generate random numbers like this:

  puts (1930...1950).random

(For some reason this gives "warning: (...) interpreted as grouped 
expression"; I don't know why. Maybe someone more experienced could 
explain.)
