Who nominates the 12 members of the Rajya Sabha?

The President nominates 12 members to the Rajya Sabha from people who have special knowledge or practical experience in art, literature, science and social service. The rationale behind this principle of nomination is to provide eminent persons a place in the Rajya Sabha without going through the process of election. However, the American Senate has no nominated members.
