Sci-fi lovers were distraught to learn of the passing of Leonard Nimoy. Best known for playing Spock in the Star Trek franchise, Nimoy played the most iconic character in the series for nearly fifty years.

Dying from pulmonary obstructive disease, Nimoy clocked in at the old age of 83. Leading a full life, he acted in 103 episodes of Star Trek, as well as eight Star Trek movies, including the recent JJ Abrams reboots.

Nimoy also directed Star Trek V and VI. Spock is undeniably the most famous humanoid alien. Even people not fans of Star Trek recognize the hand symbol, derived from Jewish priestly rituals. Everyone recognizes the term “Live long and prosper,” no matter how familiar with Star Trek one is.

Nimoy was undoubtedly a pioneer in the field of sci-fi alien culture, retaining the human element of being driven by morals and connections while being a highly intelligent and calculating Vulcan that uses his knowledge to help the crew of the USS Enterprise.

Costar William Shatner said “I loved him like a brother […] we will all miss his humor, his talent, and his capacity to love.”

Clearly Shatner left a profound impact on his coworkers. Shatner played Captain Kirk, the main lead, while Nimoy was the colead.

Also starring in Star Trek was George Takei, playing Sulu the pilot of the Enterprise. Takei said “The word extraordinary is often overused, but I think it’s really appropriate for Leonard. He was an extraordinarily talented man, but he was also a very decent human being.”

Clearly, Nimoy has left an impact on the genre of sci fi and will be sorely missed.
