Leonard Nimoy was an American actor, director, photographer, author, and singer/songwriter. He is best known for his role as Spock in the Star Trek franchise.
Nimoy supported numerous charitable causes throughout his life, including Biet T'Shuvah (Addiction Recovery), the COPD Foundation (Chronic Obstructive Pulmonary Disease), and The Nimoy Foundation (Fine Arts).
Leonard Nimoy played Spock for nearly five decades, garnering him numerous awards, a place among TV guide's 50 Best Characters, and millions of fans worldwide.
Spock's iconic Vulcan Salute was devised by Nimoy and premiered in the season two episode "Amok Time." The salute is based on a gesture used in a priestly blessing in the Jewish faith, and has become the universal sign for "Live long and prosper."
The Vulcan Salute is made by raising the hand with the palm facing out, extending the thumb, and parting the fingers between the middle and ring finger.
