Ludwig Bauer has died aged 97.
He used to have a Wiki page (before it got deleted).
Mentioning him because I think there is now a very small handful of Knights Cross recipients still living.
The only two I know by name:
*Gerhard Sommer, turns 99 this month
*Hugo Broch, 98, who people better know as the Luftwaffe ace who got to fulfil his life-long dream of flying in a spitfire aged 95, with the help of Dan Snow
