Daniel M. Tellep, an aerospace engineer who initiated a merger between Lockheed and Martin Marietta to kind the world’s largest army contractor, then grew to become its first chief government, died on Nov. 26 at his dwelling in Saratoga, Calif. He was 89.
His loss of life was confirmed by his daughter Susan Tellep.
Mr. Tellep was at Lockheed’s helm because the Cold War was ending. Lockheed, primarily based in Calabasas, was struggling and looking out at doubtlessly diminished demand with the comfort of worldwide tensions, as was Martin Marietta, led at the time by Norman R. Augustine. The merger, in 1995, created a protection business behemoth. In 2019, Lockheed Martin web gross sales had been $59.eight billion.
“The ‘merger of equals’” that he orchestrated between Lockheed and Martin “led to innovations and capabilities that continue to protect our nation, our allies, and our highest ideals,” Marillyn Hewson, Lockheed Martin’s government chairwoman, stated in a press release after Mr. Tellep’s loss of life.
As a chief government at Lockheed after which at Lockheed Martin, Mr. Tellep oversaw improvement of army communications satellites, photographic intelligence satellites, the Hubble Space Telescope and extra.
As an engineer at Lockheed, he was a pioneer of house and missile know-how techniques. He was the principal scientist on the nation’s first re-entry flight experiments, performed to find out how a nuclear missile may finest undergo the ambiance, into house after which again into the ambiance with out being destroyed. He additionally labored on submarine-launched ballistic missile techniques and on producing thermal tiles to guard house shuttles.
“He had a lot of knowledge of how to keep things from burning up, basically,” his longtime colleague David Klinger stated in a telephone interview. “He was very good at the mathematics as well as the practical side to actually make things work. And he was so good that the company put him in charge of more and more people.”
Daniel Tellep was born on Nov. 20, 1931, in Forest City, Pa., about 25 miles northeast of Scranton, to John and Mary Tellep. His father labored as a coal processor after which as a carpenter. His mom, who had immigrated from Eastern Europe as a baby, labored for a thread firm. The household later moved to San Diego, the place his father labored as a machinist and the place Daniel grew up.
Daniel was obsessive about flight from a younger age, when he started creating a lifelong ardour for mannequin airplanes; in a memoir he wrote for his household, he recalled constructing his first:
“No doubt the finished model was crude, but there it was, three-dimensional, recognizable as one of the popular airplanes of the era, and I could hold it out on my arm and move it as if it was in flight. I remember looking at it for hours.”
He studied mechanical engineering at the University of California, Berkeley, graduating summa cum laude in 1954 and incomes a grasp’s diploma in 1955. He joined Lockheed that yr. He was the principal scientist on the X-17, one of many earliest analysis rockets.
Mr. Tellep’s work in re-entry know-how and thermodynamics gained him, at 32, the Lawrence B. Sperry Award from the American Institute for Aeronautics and Astronautics. He was later elected to the National Academy of Engineering.
Rising by way of Lockheed’s ranks, Mr. Tellep was named president in 1984 and chairman and chief government in 1989. The firm had been struggling, and he helped flip it round. He was in cost when it gained a big contract to construct the F-22, the most recent era of Air Force fighter planes at the time. The contract translated to $70 billion in income for the corporate and its companions and solidified Lockheed’s company rebound.
He management was seen.
“Throughout Lockheed’s travails over the past several years, Mr. Tellep has maintained his characteristic outward calm and affability,” The New York Times wrote of him in 1991, “though he proved himself to be as tough as the most ruthless corporate raider.”
Mr. Tellep became Lockheed Martin’s first chairman and chief executive in 1995, serving as C.E.O. for nine months and remaining as chairman until 1998.
He met Margaret Lewis, in college and married her in 1954. The couple had four girls and later divorced. He met and married Patricia Baumgartner, a psychotherapist, in 1970. They remained together until her death in 2005.
In addition to his daughter Susan, he is survived by his three other daughters, Teresa and Mary Tellep and Patricia Axelrod; his first wife, with whom he remained close; two stepdaughters from his second marriage, Chris Chatwell and Anne Bossange; seven grandchildren; and five great-grandchildren.
Mr. Tellep’s passion for flight extended into his adult years, when he would take to the sky in engineless gliders, a pursuit requiring deep knowledge of wind and thermodynamics. He flew radio-controlled airplanes into his early 80s. And the model planes he built as a boy, including a treasured one he lost, remained in his memories.
“On a hot summer day, I launched the glider,” he wrote in his family memoir, “and it seemed to circle forever, barely descending. This was when I learned about ‘thermals.’ This rising column of air carries with it all things light — and this included my glider. Since I didn’t put my name on it, there was no way it could be returned. Now, so many years later, it is with me in a different way.”
