Two images taken from the BBC clip of John Harper's gravestone
I was kindly sent a link to a BBC Scotland news item from April 2012, the centenary of the Titanic disaster that claimed over 1500 lives.
The news clip recalls John Harper, the very brave pastor from the Walworth Road Baptist Church, who gave up his life jacket in the freezing Atlantic waters so a fellow passenger could be saved. Later, his home church in Glasgow was renamed the Harper Memorial Church in his honour.
Further details of Harper and that fateful night can be found here.
Grateful thanks to Julia Honess for the link.
