Actress Elisabeth Sladen, possibly the performer who has maintained the longest on-screen association with a Doctor Who character in the history of the franchise, dies at the age of 65. In 1973, the producers of Doctor Who had hired another actress to play the part of new companion Sarah Jane Smith, only to meet with strenuous objections from series lead Jon Pertwee. Elisabeth Sladen was then cast in the part, continuing to play Sarah Jane through 1976, one of the longest-running companions in the original series. Numerous times she had been approached to reprise her role, only agreeing to do so in 1981 in her own spinoff, K-9 & Company, which never made it past the pilot stage. After reprising the role of Sarah Jane for Big Finish’s audio spinoff series centered around the character, she was asked to play the part again – on television – alongside David Tennant, sparking new interest in the character and ultimately leading to her own spinoff series, The Sarah Jane Adventures. Filming of the fifth season of that series had been put on hold while she was admitted to the hospital.
Actor William Campbell, who guest starred as Koloth the Klingon in the classic Star Trek fan favorite The Trouble With Tribbles (and reprised the role in the much later Deep Space Nine epsiode Blood Oath), and played the Q-like Trelaine in The Squire Of Gothos, dies at the age of 84.
Ralph McQuarrie, the artist who envisioned key scenes and settings of the 
Caroline John, who joined the cast of Doctor Who for only a single season (also the show’s first season in color), accompanying incoming third Doctor Jon Pertwee as the Doctor’s scientific assistant Liz Shaw, dies at the age of 72 due to complications from cancer. Despite her brief connection to the series, Caroline John has remained associated with Doctor Who, from reprising the role of Liz Shaw repeatedly for Big Finish Productions, to making a cameo appearance in 1983’s The Five Doctors, to reviving Liz as the head of a secret scientific think tank in the fan-made PROBE video series of the 1990s.
Actress Mary Tamm, who appeared in a single (but very high-profile) season of Doctor Who as the first incarnation of the Time Lady Romana, dies at the age of 62 after a battle with cancer. Having revived her version of the Romana character in recent years for Big Finish Productions’ Doctor Who audio stories (and the spinoff series Gallifrey), Tamm has remained popular with fans and has also recently completed her autobiography. Several days later, mere hours after delivering a eulogy at her memorial service, her husband of 34 years, Marcus Ringrose, also dies of a heart attack.
American astronaut – and the first human being to walk on the surface of the moon – Neil Armstrong dies at the age of 82. On July 20th, 1969, he took the “giant leap” onto another world that instantly made him perhaps the most famous citizen of the 20th century – moreso than the Beatles, more than Hitler or Churchill, more than any actor. That century will be defined by the exploration of the moon forever, and as many men walked on its surface, Armstrong’s will be the name that is forever associated with that exploration.
Michael O’Hare, who starred in the 1993 pilot movie and the first full season (1994) of the science fiction series Babylon 5, dies of complications from a heart attack he suffered the week before. An accomplished stage actor who made infrequent forays into television, O’Hare had been out of the public eye (including the science fiction convention circuit) for several years.
Legendary UK television producer Gerry Anderson, responsible for a string of puppet-based hit shows such as Thunderbirds, Supercar, and Stingray, and such live-action cult classics as UFO, Space: 1999, and Space Precinct, dies at the age of 83. Additionally, the Century 21 comics magazine (an extension of his company, Century 21 Productions), had provided the first-ever Doctor-less comics featuring the Daleks in the 1960s, arguably the birth of Doctor Who’s “expanded universe.” At the time of his death, there have been numerous attempts by others to modernize his concepts, with wildly varying degrees of success.
Legendary makeup artist and creature designer Stuart Freeborn, whose most enduring cinematic creations include Yoda and Jabba the Hutt from the original Star Wars trilogy, dies at the age of 98. His numerous big-screen credits include Dr. Strangelove, 2001: a space odyssey, The Omen, the entire original Star Wars trilogy and all four of the Christopher Reeve Superman films.
The original designer of the seemingly immortal Dalek casings seen throughout the history of Doctor Who (and its associated merchandising), Raymond Cusick dies at the age of 84. A young staff designer at the BBC in 1963, Cusick landed the assignment of originating the Dalek design by chance when another staff designer originally assigned to Doctor Who, Ridley Scott, changed assignments. Years later, after quietly enquiring about sharing some of the windfall from Dalek merchandising, Cusick received a thank you note from the BBC, along with a check for 250 pounds. Despite this, he continued as a television production designer for the BBC through the late 1980s.
SF/horror/fantasy author Richard Matheson dies at the age of 87. His novels and short stories have been fodder for Hollywood for over half a century, including I Am Legend (which, in addition to the Will Smith adaptation, had also been translated into The Last Man On Earth and The Omega Man, and is often credited as a primary influence in zombie fiction), What Dreams May Come, Somewhere In Time (inspired by the story “Bid Time Return”), A Stir Of Echoes and Duel (which inspired a TV movie which was Steven Spielberg’s first major directorial effort). Matheson also wrote episodes of 
The president of Nintendo through the latter half of the 20th century, Hiroshi Yamauchi, dies at the age of 85. Having dropped out of college to assume control of Nintendo from his ailiing grandfather in 1949, Yamauchi transformed the company from a maker of playing cards into a power player in the electronic game market, even though Nintendo’s first video game product was a licensed version of the American-made Magnavox Odyssey. Twice, Yamauchi boldly decided to break into the American video game market with no guarantee of success: once with the arcade game Donkey Kong, and again with the launch of the Nintendo Entertainment System, even after a Stateside licensing deal with Atari fell through at the last minute, depriving the NES of Atari’s existing marketing and distribution channels.
Scott Carpenter, Mercury astronaut and the 
Director Cliff Bole, a Hollywood veteran with episodes of such classic shows as The Six Million Dollar Man, MacGyver, and Spenser: For Hire under his belt, dies at the age of 75. Best known for his very frequent returns to the Paramount lot, Bole directed episodes of Star Trek: The Next Generation, Deep Space Nine and Voyager, including the all-time fan favorite TNG two-parter The Best Of Both Worlds (1990). He also directed other genre shows such as The X-Files, Supernatural, and Millennium.
Shuttle astronaut Dale Gardner, who flew aboard space shuttle Challenger’s 
Writer, director and actor Harold Ramis dies after several years of battling vascular disease. An SCTV comedy veteran who went on to co-write Stripes, Animal House and Caddyshack, Ramis gained genre fame in 1984 for co-writing Ghostbusters, and starring in it as Dr. Egon Spengler, the brains of the ghostbusting operation. He did both again for the less successful Ghostbusters II in 1989, but went on to write and direct such films as Groundhog Day and Analyze This. Ramis was 69.
The creator and programmer of Lode Runner, Douglas E. Smith, dies at the age of 53. A spare-time creation that became an all-consuming passion for Smith, Lode Runner sparked a nearly unprecedented bidding war among major computer game publishers in 1983. At the time of Smith’s death, Lode Runner has been ported to most major game and computer systems over the past 31 years.
Doctor Who audio actress Maggie Stables, who originated the role of the first TARDIS traveler unique to the audio medium, dies after a lengthy illness. First appearing in a guest role in Big Finish Productions’ inaugural Doctor Who story, The Sirens Of Time, in 1999, Stables was quickly cast as Dr. Evelyn Smythe, a new companion for the sixth Doctor (Colin Baker) who defied the series’ convention of casting young actresses in such roles. Ms. Stables reprised the role intermittently, making her final appearance in a trilogy of stories released by Big Finish early in 2011; the character appeared in animated form in a 2002 webcast, but never appeared on television.

Four-time Emmy winning film and TV director Joseph Sargent, who directed the influential Star Trek episode 
Actor Barrie Ingham, one of the few actors to have played speaking parts in both the Doctor Who and Star Trek franchises, dies at the age of 82. Having appeared alongside William Hartnell in the 1965 
Actor Leonard Nimoy, known for nearly half a century as the face and voice of 
Actress Grace Lee Whitney, a familiar face of ’60s TV who had a recurring role in the first season of Star Trek as Yeoman Janice Rand, dies at the age of 85. Compared to most of her castmates, her brief tenure aboard the Enterprise was tumultuous, ending just eight episodes into her stint as an intended semi-regular character. Her dismissal from the show led to a career downturn and battles with alcohol addiction, from which she recovered, reprising the role of Rand in cameo scenes in several of the Star Trek films, an episode of Voyager, and the Hugo-nominated fan-made episode World Enough And Time in 2007.
A renowned film music composer whose early sci-fi works put him on the map, James Horner dies at the age of 61 in the crash of his private plane. After his 
Dr. Claudia Alexander dies at the age of 56, while still serving as the chief scientist of a suite of U.S.-provided instruments aboard ESA’s history-making Rosetta mission. Renowned as one of JPL’s finest research scientists, she was a member of the Galileo plasma instrument science team before becoming, by the mission’s end in 2003, the project manager of that mission to Jupiter.
Nintendo of Japan CEO Satoru Iwata dies as a result of complications from gall bladder surgery. As the head of game developer HAL Laboratories, Iwata oversaw games in the Kirby, Super Smash Bros. and Pokemon series, until he replaced outgoing Nintendo CEO Hiroshi Yamauchi in 2002. His tenure saw the introduction of the Nintendo DS handheld, the Wii console, and the wildly popular Amiibo figurines, as well as unprecedented interaction with fans and customers on the internet.
Writer George Clayton Johnson, who co-wrote the 1967 novel Logan’s Run with William F. Nolan and wrote episodes of both The Twilight Zone and Star Trek, dies at the age of 86. As part of the legendary “Green Hand” collective of golden-age SF writers, Johnson penned his stories in the company of such fellow southern California writers as Ray Bradbury, Harlan Ellison, Richard Matheson, Jerry Sohl, Robert Bloch, and Rod Serling (who paid Johnson for his first produced television work). For 
On the eve of the 45th anniversary of the Apollo 14 moon landing, astronaut Edgar “Ed” Mitchell dies at the age of 85. The sixth human being to set foot on the moon, Mitchell accompanied Alan Shepard to the lunar surface aboard the Apollo 14 lander. Following his visit to the moon, Mitchell had become interested in researching human consciousness and extra-sensory perception, but later surrounded himself with controversy by claiming that he was certain that UFOs had visited Earth.
