Herbert Sigmund Eisner (23 June 1921 – 28 June 2011) [1] was a British-German scientist whose work led to high-expansion fire fighting foam. He was also a playwright.
He was born in Berlin.
His paternal grandfather knew the composer Richard Strauss his maternal grandfather founded Germany's first department store, the Grand Bazaar, in Frankfurt. His mother was a Wagnerian singer who knew the playwright Bertolt Brecht. The family lived near the Tiergarten (Animal Garden) in central Berlin, and as a result often saw Joseph Goebbels walking to work. His aunt was Lotte H. Eisner, a German-French film critic, notably of German Expressionism, and a friend Leni Riefenstahl, the film director.
In 1936 he was sent to Buxton College, a boys' grammar school in Derbyshire. His parents left Berlin in 1939 and moved to London.

He worked for most of his life at the Safety in Mines Research Establishment (SMRE) in north-west Derbyshire until 1981.
