|Prof. Mark Moogalian, 51, from Midlothian, Va. Apparently he teaches English at the Sorbonne.|
"Mr Moogalian, who lives in Paris but is originally from Midlothian, Virginia, US, is the previously unnamed man who came to the aid of “Damien A”, 28, a French banker who confronted El-Khazzani.
The academic acted instinctively to protect his wife Isabella Risacher, who was also aboard the Thalys train.
He tackled the Kalashnikov assault rifle off El-Khazzani, who then drew a sidearm and shot him in the neck before taking back the rifle, his sister has revealed.
Three other US citizens including two military personnel, and Chris Norman, a British businessman then stepped in to disarm and overpower the assailant.
Mr Moogalian’s sister Julia said: “He made sure his wife was hidden behind a seat. She watched the whole thing happen.
“He did manage to get the weapon away from the gunman.
“But the gunman then pulled another gun and shot my brother.
"There's a video of him saying 'help me' - he thought he was losing so much blood he would die.
"He's in extremely good shape - he cycles miles and runs - so we think that stood him well for this.
"The French President has reached out to ask him to come to dinner when he is fit enough."
The academic, a keen musician and cyclist, was shot in the back of the neck and the bullet passed through his body causing nerve damage, his sister said."
