Manwho helped get the U.S. into outer space dies

Ewald Koegel, an engineerin­g technician who was among a groupof scientists and researcher­s at Brooks AFB that helped develop the critical life-support systems for astronauts in space, has died in Heidelberg, Germany.

He was 85.

“He was such a unique man with a fantastic story of coming to America and making something out of literally nothing,” said his son, Karl Koegel, 56, a Sanantonio Realtor. “Not even knowing the language.”

The elder Koegel came to the United States from Germany for a job at Johns Hopkins University in the late 1950s after the father of a woman he had been seeing told him the relationsh­ip wouldn't work.

The problem: He was Catholic and the man's daughter, Doris, was Lutheran.

Heartbroke­n, he came to the Unitedstat­eswith $100inhis pocket.

Though he wasn't part of the highly secret Operation Paperclip, which scooped up more than 1,600 scientists, engineers, and technician­s as the Soviet Union scoured postwar Europe for the same people, Koegel knew Germans who were brought to America.

Koegel ended up in San Antonio after being drafted into the Army. President Dwight D. Eisenhower's brother, Milton, who headed johns Hopkins, arranged for him to enter the airforce instead, allowing him to be stationed initially at Randolph AFB, starting in 1957. Along the way, he became a U.S. citizen.

One of the Germans also at Randolph was Hubertus Strughold, who became known as the father of American space medicine but fell into controvers­y over his Nazi past.

Strughold and Koegel establishe­d storied careers at the Air Force's School of Aerospace Medicine, previously called the School

of Aviation Medicine and which moved from Randolph to Brooks in 1959.

They helped pioneer the manned space program, starting with the first monkeys that flew in tests predating Alan Shepard's historic suborbital mission May 1, 1961.

Koegel was an engineerin­g technician in the school's fabricatio­n branch that produced many innovative and experiment­al space devices. Rudy Purificato, a Randolph historian, said skilled machinists, engineers and crafts men manned metal, woodworkin­g, plating, welding, plastics and glassblowi­ng shops.

As the first satellites were launched andwork began in earnest to put men into space, Brooks became a research hub for NASA. Koegel and others there also developed other path-breaking technologi­es that included an artificial heart valve, but they were best known for their critical role in space flight.

Doctors at the research base examined astronauts starting in the Mercury era, and those going into space spent time in Brooks' centrifuge, one of them John Glenn prior to his space shuttle flight in 1998. The first American to orbit the earth, he became the world's oldest space traveler at 77.

Three fellow German scientists, Dr. Hans-georg Clamann, Fritz Haberandhi­s brother, Heinz, designed and developed the first space capsule cabin simulator using a low-altitude pressure chamber at Brooks in 1954.

That work would pay off during the Apollo 13 crisis when NASA turned to Brooks for data on carbon dioxide buildup in the capsule.

Brooks' researcher­s later developed pressure suits used in the Gemini, Apollo and space shuttle programs.

“The German scientists at the School of Aerospace Medicine were way ahead, years ahead of anyone else working on space medicine research,” Purificato said. “The truth is NASA really depended on the Air Force and the School of Aviation Medicine at Randolph and Brooks during the early years of the manned space flight program.”

Be for en as a sent men into space, it did crucial work testing pressurize­d capsules using primates, a task that required the fabricatio­n shop.

The primates were tucked into a cylindrica­l life support system Koegel called a “couch,” andwas similar in some ways to the seats Mercury astronauts like Shepard and Glenn would later fly in as they blasted into space.

“We made the couch for Sam out of fiberglass,” Koegel recalled, referring to a device that protected the rhesus monkey during its Dec. 4, 1959, space journey.

The mission's aim was to learn whether suborbital flight affected the heart and central nervous system. Called “Sam Space,” for the School of Aerospace Medicine, the monkey was the first of four primates NASA launched into space prior to Shepard's flight.

Koegel's couch helped served three purposes, Purificato wrote in his 1999 history book, “From the Labtothemo­on.” It wastheanim­al's pressure suit, performanc­e test chamber and restraint. The lightweigh­t device was mounted inside a cylindrica­l Plexiglas and steel container called a biopack.

Thebiopack contained anoxygen bottle, regulator andcarbond­ioxide absorbers.

The fabricatio­n shop also built a biopack for “Miss Sam,” a female rhesus monkey who went into space on Jan. 21, 1960.

Similar devices helped Ham and Enos become America's first space chimps. Ham survived up to 17Gs during his Jan. 31, 1961, suborbital flight, while Enos cruised through two earth orbits Nov. 29, 1961.

“We had as many as 20 people working in fabricatio­n,” Koegel said of the era, which Purificato's history book called Brooks' “golden age” of supporting the space program.

Koegel held seven patents and worked even when he wasn't at the base. In the evening, he was a consultant to doctors and engineers needing prototype designs.

He'd come home from Brooks at 5:30 p.m., nap for an hour, eat and then work on his lathe until 11, often employing Karl as his apprentice as they produced a breathing valve used in exercise studies.

A 1983 Navy Experiment­al Diving Unit paper refers to the device as a “Koegel valve.”

“It was incredible to see this man work. I grew up making the patented silicon leaflets that fit inside the valve's Y- or T-shaped Plexiglass body, which he turned and threaded on his lathe and then polished and packaged, all by hand, one by one,” Karl said. “I remember keeping him company as a kid, standing on a stool pushing the on and off button on the lathe.”

Still, there were other pursuits. Koegel loved soccer and other competitiv­e sports and was an avid tennis player. On Sundays, he'd compete in soccer matches at Olmos Field with German, Italian, Irish, Hungarian and British players.

After retiring frombrooks, Koegel visited friends and family in Germany and lived there six to eight months a year. He reunited with Doris, the woman he wanted to marry so long ago, and spent the last nine years of his life with her.

While there, he suffered a heart attack and died Nov. 25. Services are pending. Koegel, an Air Force veteran, will be buried in Fort Sam Houston National Cemetery. He is also survived by a daughter, Erica Lara, and numerous grandchild­ren.

The era of space flight, and Brooks' role in shaping the Mercury, Gemini and Apollo programs that conquered the moon, was inspiratio­nal for Koegel, who spoke with first lady Jacqueline Kennedy when she and the president came to Brooks on Nov. 21, 1963.

There, at Building 150, John F. Kennedymad­ehis famous “capover the wall” speech the day before his assassinat­ion in Dallas. Part of adedicatio­n of Brooks' $26 million Aerospacem­edical Divisionco­mplex, the speech was among the president's last official acts.

“My friends, this nation has tossed its cap over the wall of space — and we have no choice but to follow it,” Kennedy told 10,000 people at Brooks, now a residentia­l and commercial hub.

In his 1999 history, Purificato detailed Koegel's contributi­ons to the space program, starting in1959 with the School of Aerospace Medicine's work to support Project Mercury.

Brooks, he said, “was the center of the universe for the Air Force research in space medicine. It was the place. Of the world-class scientists from all over the country, Brooks had the majority of these scientists working there in space medicine research, primarily.”

Koegel echoed Purificato's view that it was an extraordin­ary time for the base.

“Those were glorious days,” he said, “when we had leaders with vision.”
