Hawking famously divorced his first wife Jane Hawking in 1990, and married his nurse Elaine Mason five years later.
She had been married to David Mason, the engineer who attached the speech synthesizer to Hawking's wheelchair.
Cambridge police investigated allegations that his second wife abused him, and his former assistant told Vanity Fair in 2004 Hawking only suffered injuries when he was alone with Elaine.
But Hawking shot down the allegations, and the investigation was eventually dropped with no charges filed against his wife.
The two divorced in 2006.
