The name Aikido only existed after 1940, before that it was Aikibudo or Aikijujitsu. That was made clear in several of the above posts and any history you read.

There is a lot more in depth information available on the internet and books than the few minutes Ah Loi Lee sensei was able to cover.
saposedly o-sensi learn aiki-jutsu before making aikido. i saw that on a video from Sensi DR. Lee Ah Loi
