The Grim Reaper struck Star Trek often and hard in 2015. and Trek fans across the globe spent far too much time this past year mourning the losses of beloved actors and behind-the-scenes figures who contributed mightily to the franchise over the past 50 years, including one of its most-legendary, iconic pillars, Leonard Nimoy. Today, we take an additional moment to remember those we’ve lost.

Leonard Nimoy, Star Trek’s Spock, died on February 27. Nimoy -- an actor, writer, producer, director, poet, host, voiceover artist, photographer, patron of the arts, philanthropist, husband, father and grandfather -- succumbed to the end stages of COPD (Chronic Obstructive Pulmonary Disease), an illness that resulted from years of smoking and which afflicted him despite having quit smoking more than three decades ago. In 2014, he announced via Twitter that he was battling COPD and frequently implored fans to stop smoking before it was too late. Nimoy, of course, played the half-human/half-Vulcan Spock in The Original Series, The Animated Series, The Next Generation, the six TOS feature films, Star Trek (2009) and Star Trek Into Darkness. He also directed The Search for Spock and The Voyage Home and produced and developed the story for The Undiscovered Country

Beyond Trek, Nimoy's many film, TV and stage credits included Mission: Impossible, A Woman Called Golda, In Search Of..., Equus, Never Forget, Vincent, Standby: Lights! Camera! Action!, The Simpsons, Transformers: Dark of the Moon and a juicy, late-career recurring role on the J.J. Abrams-produced series Fringe. He also directed such features as Three Men and a Baby, which was a huge hit, and The Good Mother, a drama that he always spoke of with tremendous pride. With his friend and TNG's Q, John de Lancie, he created Alien Voices, which staged and recorded radio play-style productions of classic and original sci-fi/fantasy stories. And yes, who could forget Nimoy's music pursuits, which included several albums and such tunes as "Proud Mary" and "The Legend of Bilbo Baggins"? Nimoy joined Twitter in 2010 and gave William Shatner a run for his money, tweeting more than 1,700 times and amassing more than one million followers.

Back in May 2012, teased Nimoy about being the busiest retired man in history. Asked if he truly considered himself retired, Nimoy replied, "Yeah, I do. I am. Look, I liken myself to a steamship that's been going full-blast and the captain pulls that handle back and then says, 'Full stop,' but the ship doesn't stop. It keeps moving from inertia. It keeps moving. It keeps moving. It'll start slowing down, but it doesn't stop. It doesn't come to a dead stop. That's the way I am. I still have a few odds and ends things that I enjoy doing. I don't want to get up in the morning and have nothing to do that day. That would be boring." Perfectly logical, right? And in a touching final tweet, which he posted on Feb. 23 and with which he was likely bidding farewell, Nimoy wrote, "A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP.”

Harve Bennett, a veteran Star Trek writer and producer, passed away on February 25 at the age of 84, two days before the death of Leonard Nimoy, with whom his career intersected -- to the everlasting benefit of both men and fans everywhere. He’d retired to Oregon years ago and died there following a long illness. Bennett produced and co-wrote the story for The Wrath of Khan, which was a success financially, critically and with Trek fans and is widely credited with saving the franchise, as Paramount Pictures had serious doubts about Trek's future following the costly The Motion Picture. Bennett subsequently produced and co-wrote the stories for The Search for Spock, The Voyage Home and The Final Frontier. Bennett also made a memorable cameo appearance in The Final Frontier, playing Starfleet Chief of Staff Admiral Robert Bennett.

The Chicago-born Bennett was already a successful writer-producer by the time he beamed into the Trek universe. Among his credits were Mod Squad, The Invisible Man (1975 version), Rich Man, Poor Man, The Gemini Man, The Six Million Dollar Man, The Bionic Woman and Salvage 1. During and after his run with Trek, Bennett wrote and/or produced A Woman Called Golda (with Leonard Nimoy co-starring opposite Ingrid Berman), The Jesse Owens Story, Time Trax and Invasion America., in a 2010 interview, asked Bennett what he thought his most significant contributions to Trek were. He replied candidly, saying. "I resurrected the franchise (at the time). That would be my contribution. There might not have been another Star Trek and certainly there would not have been spinoffs had not Star Trek II been such a very viable hit.”

Grace Lee Whitney, the actress and singer who played Yeoman Janice Rand on TOS, several of the TOS features and also on Voyager, died on May 1 at the age of 85, passing away peacefully in her home in Coarsegold, California. Whitney, a blue-eyed blond beauty, represented one of Trek’s greatest cautionary tales and also one of the franchise's most satisfying renaissance stories. She played the deeply professional Rand in eight first-season TOS episodes before being dropped from the series and slipping into an abyss of drugs and alcohol that left her, quite literally, on Hollywood’s Skid Row. She finally got help, found God, and reclaimed her life and career, with an assist from Leonard Nimoy, and spent decades helping others overcome their own addictions.

During an interview with in 2011, Whitney spoke excitedly of living on a 30-acre property near Yosemite National Park, with a running creek, and helping to care for her grandchildren. "(My son) Jonathan built a home down at the end of my property, where he lives with his family, including my grandchildren," she enthused. "They’re going to take care of me as I move through life to my home in heaven. But right now I take my grandchildren to school and cart them around, and I’m of maximum service to them... I also line dance one night a week and I go to the gym three days a week. So, my life is happy, joyous, free, sober and saved, and a lot of fun, too. I have a lot of fun."

George Coe, a veteran actor, Screen Actors Guild activist and TNG guest star, passed away on July 18 at the age of 86.

Law, Smallville, The West Wing, Curb Your Enthusiasm, Star Wars: The Clone Wars, Supernatural, Two and a Half Men, and Archer.

Penny Juday, longtime Star Trek art department coordinator who served the franchise as an archivist, passed away on December 19 at the age of 60. During her Trek days, which spanned from The Undiscovered Country to Nemesis and included all seven seasons of Deep Space Nine, Juday wore many hats. She worked directly for Herman Zimmerman on Generations, First Contact, Insurrection and Nemesis. As Trek archivist (on the Paramount Pictures backlot), she kept track of everything and anything Trek-related: sets, props, photos, blueprints, miniatures/models and more, and was the go-to person for production staffers when they required information or the actual items.

Anderson teamed with Gene Roddenberry in 1964 to create the transporter beam effect and other VFX for the first Trek pilot, "The Cage" and also "Where No Man Has Gone Before." The company's additional contributions included shots of phasers firing and exterior shots of the Enterprise warping through the stars.
