Orson Welles's brother Richard

[Anthony]

Hello everyone,

I'm new to this forum, and since a year or so became interested in the life and work of mr. Welles.
Now i have some questions about Welles's brother Richard of which there is not so much information kown to me.
Can someone tell me who he was? and in which books about Orson Welles he is mentioned and/or what is particurly khown about?
I, myself do khow the following things of which i am not sure, maybe somebody can give me a true/false about them:

1) He was shy, whitdrawn, clumsy?
2) He went to the same school as his younger brother Orson later went, but failed at school?
3) Orson didn't like him?
4) The most important: was he a schizofrenic?

Maybe someone has got a photograph of him?

I, hope someone can help me with mine questions

Regards, Anthony
