Friedrich Gitterfenster

Classical composer from A Clockwork Orange (novel by Anthony Burgess), 1962.

...it was like for a moment, O my brothers, some great bird had flown into the milkbar, and I felt all the malenky hairs on my plot standing endwise and the shivers crawling up like slow malenky lizards and then down again. Because I knew what she sang. It was from an opera by Friedrich Gitterfenster called Das Bettzeug, and it was the bit where she's snuffing it with her throat cut, and the slovos are "better like this maybe." Anyway, I shivered.

"Gitterfenster" is German for a lattice window.
