The founder and team principal of Williams F1 has been around the sport for a long time and received support worldwide for a quick recovery.
"I am very pleased and happy to say that he is now back home, and back at the factory with us," she told reporters at the team’s Grove HQ. "He came out of hospital on Monday."
"As everybody is aware now, he contracted pneumonia after the Italian GP at Monza and he has been in hospital ever since the start of September."
"It was a slow recovery," she admitted, "but I am really pleased to say that he is pretty much back to the old Frank that we know and love, so it is lovely to have him back with us at the team."
