I love Berlioz.
Had anyone before him instructed the violins to play with the backs of their bows? (Witches' Sabbath, Symphonie Fantastique).
Has anyone since?
As Martle points out, thousands of composers since Berlioz have used this technique. The first recorded use of it as far as I know was in Tobias Hume's collection of viol pieces
Musicall Humours, published in 1605.
At a concert last night I heard Biber's
Battalia a 10 in D of 1673. Col legno was used in that to produce a warlike effect. In fact it was a curious piece all round, with a very discordant episode representing soldiers singing various songs at once, and paper inserted between the strings of the double bass to make it sound more like a drum.
