It sparked a subculture that had fans discussing the evils of Klingons and the geography of Vulcan. More than 40 years later, “Star Trek” still has legions proudly sporting their pointy ears at science fiction conventions across the country. Preston Hollow neighbor Richard Jefferies doesn’t qualify as a full-fledged “Trekkie”, but the show still holds a special place in his heart. That’s because his brother, Matt, was the mastermind behind several of Star Trek’s spaceships, including the famed Starship Enterprise. “My brother was a great aviation artist,” he says. “It all started when he was 14. We got kind of wild at a construction site and ended up in the hospital with a broken leg. He started drawing to pass the time, and it just took off from there.” Now Jefferies has recounted his late brother’s life in a new book, “Beyond the Clouds”. And while he admits it’s certainly interesting to read about his brother’s work on shows like “Star Trek”, “Little House on the Prairie” and “Dallas”, Jefferies says the book has some larger themes, too. “I definitely wanted to honor my brother with this book. But I also want people to read it and realize that if they have a dream and pursue it relentlessly, they can make it happen with hard work. My brother was proof of that.”
