Aikido was created by Morihei Ueshiba (Ueshiba Morihei, 14 December 1883 – 26 April 1969), referred to by some aikido practitioners as Ōsensei (“Great Teacher”) or simply “The Founder”. Ueshiba envisioned aikido not only as the synthesis of his martial training, but as an expression of his personal philosophy of universal peace and reconciliation. During Ueshiba’s lifetime and continuing today, aikido has evolved from the Aiki that Ueshiba studied into a wide variety of expressions by martial artists throughout the world.
Here is footage that survives from 1935 of Morihei Ueshiba. If these few minutes are of interest, you will be able to find the full footage available elsewhere on the web. There is a wealth of other footage of the Founder available, and although it shows a transition of styles, it is a wonder to watch!
