Nathan Alterman (Hebrew: נתן אלתרמן) was an Israeli poet, playwright, journalist, and translator.
In 2001, director Eli Cohen made a film about him, Altermania, which won the prestigious Wolgin Award at that year's Israeli Film Festival. In the promotional materials for the film, Alterman is described as a "double personality" who was by turns "charismatic, clever, rational, and bright" and a "gloomy skeptic," a man perhaps "bedeviled by a death wish," a fighter "for justice" who nonetheless abused "those closest to him." The film asks the question, "Did he fight for the rights of Arabs or did he believe in a Greater Israel?" calling him a "tortured man full of contradictions." The only answers lie somewhere in the works Alterman left behind.
