An (almost) unseen photo from the archives at La Scala which shows an emotional Maria Callas moved to tears by the incredible success of her Lucia di Lammermoor as the curtain closes mid-performance. With Herbert Von Karajan
Herbert von Karajan (born Heribert, Ritter von Karajan;( 1908 – 1989) was an Austrian orchestra and opera conductor. To the wider world he was perhaps most famously associated with the Berlin Philharmonic, of which he was principal conductor for 35 years. His great-great-grandfather, Georg Karajan, was born in Kozani, a town in the then Ottoman province of Rumelia (present West Macedonia in today's Greece), leaving for Vienna in 1767.
