Ueshiba only had one student who understood him, founded the one true style of Aikido which I study. All of you are just wrong...
Many students followed Ueshiba. Some founded their own styles of Aikido such as Aikikai, Yoshinkan, Shodokan, Imawa, Ki, etc... Ueshiba continued to teach his Aikido till he died. No one is teaching Ueshiba's Aikido anylonger -- apart from a small Haiitian dojo who claims to have raised Ueshiba from the grave as a zombie.
OK, I'm exhausted, fed up with mathematical fonts for mathml and thought it would be more fun than to just pass a URL to www.aikidofaq.org
and to the "search" function on this site.
