Obituary from the October 1956 issue of the Socialist Standard
We regret to have to record that our old Comrade Hardcastle passed away on September 15 at the age of 93. He was one of the only two survivors of the group that founded the Socialist Party of Great Britain in 1904.
Comrade Hardcastle attended nearly all of the Party Conferences and was present at the last one. He also attended many of the indoor and outdoor propaganda meetings, putting in a regular attendance at Clapham Common. During the last two years failing eyesight limited his attendance at evening meetings, as it was too much of a risk for him to travel far in the darkness. He was a lively, tough little man, who never lost his conviction of the ultimate success of the movement he helped to start on its journey.
In the last week of the illness that brought his life to a close his brain was still alert and he demanded news of all that was happening in the world at large—including the latest developments over Suez.
Although Comrade Hardcastle did not figure on the platform, or in literary columns, he was a staunch supporter of the Party, who did propaganda in his own way.
The final departure of a loyal old comrade is always a sad event; we send our sincere sympathy to his relatives and the expression of our own sorrow at losing him.
