Armstrong provided substantial financial and practical support towards the foundation in Newcastle of a College of Physical Science, ultimately to evolve into Newcastle University. He acted as Chairman for the College's executive committee, made generous subscriptions to the College fund and put his influential name to the subscription appeal, winning the support of his fellow local industrialists.
Armstrong laid the foundation stone of the new college building in 1887 and ten years later he presented it with the equipment which he had used to conduct his experiments into electrical discharges; the valuable equipment formed the nucleus of the Electrical Laboratory in the Physics Department of the College. After his death in 1900, the college fund became the Armstrong Memorial Fund, and it was agreed to rename the college Armstrong College in his honour.
In this letter from Robert Spence Watson, who acted as the College's legal advisor, to Armstrong, Spence Watson discusses with him matters relating to the purchase of lands for the College and the raising of subscriptions to the fund, in reply to a letter from Armstrong on the subject:
I have forwarded your letter to Professor Garnett & have asked him to write direct to you upon the subject. There can be no question that we have no money whatever to spend on speculation but if I understand the matter rightly we should be able at this site to have two acres for the price at which we could have one acre at the Singleton House site… We have not yet made any applications for subscriptions. We have one other promise of £1,000 as well as a promise of £50 a year but these have been made without any application being put out. The Council considered that we could not apply for subscriptions until we had definite plans to lay before the public. 15
