Final answer:
Tilden did not specifically do anything for the Deaf in California.
Step-by-step explanation:
Tilden did not specifically do anything for the Deaf in California. The information provided mentions a bronze memorial statue that Tilden created for Dr. Gallaudet, who founded the school for the deaf in Washington D.C. This statue represents a new method of education for those who are hearing, but it does not mention any direct contributions or actions by Tilden for the Deaf in California.
