Now, the first details about his identity emerge.
According to Schweiz am Sonntag newspaper, he was an administration chief at the Swiss helicopter rescue company that was responsible for Schumacher's transfer from intensive care in Grenoble to a Swiss rehabilitation clinic.
The man was reportedly a 54-year-old German who lived quietly with his girlfriend in the Swiss canton of St Gallen.
A long-time friend, who said he went sailing with the "trustworthy" German only six weeks ago, reportedly said he was someone who "never spoke about money worries".
"He was as he always was," the friend added. "I never would have thought he was capable of something like that."
Meanwhile, the major German newspaper Bild claims Schumacher's wife Corinna will be a patron of the forthcoming World Equestrian Games in France.
