A SHORT HISTORY OF A REMARKABLE MAN
Dr. GOETHE LINK


The Observatory He Built and His Association with the Indiana Astronomical Society (IAS)


Dr. Goethe Link was born to William H. and Phebe (Stone) Link in Warrick Co., Indiana on May 20th, 1879. His unusual first name was given to him by his father who was reading Johann Wolfgang von Goethe’s book titled Faust at the time of his birth. Goethe is pronounced “Ger-ta”, but his given name was sometimes “Hoosierized” as “Gay-tee”. He began his college career at Wabash College, but during his sophomore year, over two-thirds of the student body and faculty left because of the over-bearing control of the college’s president; hence he and several of his classmates transferred to Indiana University in Bloomington for the fall term. During his college days in the mid-1890’s, Goethe competed for five years in professional bicycle races. The first place finisher of these races was paid with $35.00 worth of diamonds, and he collected his fair share as he won quite a few races throughout the Midwest. Even the Rambler Bicycle Company of Chicago sought his endorsement for one of their newer models. Although not a racing bicycle, a 1916 Schwinn touring model with wooden wheel rims hangs above the door to the auditorium in Link Observatory as a tribute to Dr. Link’s racing skills. This bicycle was found in the greenhouse on the Links’ property.

After graduating from I.U. in 1898, Dr. Link continued onto the Central Medical College in Indianapolis from where he graduated in 1902. He then interned at City Hospital (now Wishard) the next year. Then at the age of 24, Dr. Link established a medical practice with his father on Virginia Avenue in the Fountain Square area in Indianapolis. His first thyroidectomy occurred in 1911 which was also the year he married his first wife, Clara, who was a graduate nurse at the time. A pioneer in the field of thyroid surgery, he performed over 22,000 such surgeries during his career. His last surgery before he fully retired was performed at the age of 88 years! Dr. Link was also one of the 16 physicians who helped establish the I.U. School of Medicine and organized the I.U. Medical Society. Although he is most well known for his pioneering activities in medicine, Dr. Link had many passions including amateur astronomy.

Besides bicycle racing, Dr. Link also raced gas-filled balloons as an aeronaut. He credited his bicycle training for helping him through the hypoxia (lack of oxygen) felt at high altitudes. Goethe and his partner won the 1909 National Balloon Race that Carl Fisher used to promote the 1st running of the Indianapolis 500. Dr. Link reported that they were shot at several times as they flew over Kentucky before finally landing in Tennessee. That 1st place trophy from this race currently resides at the Smithsonian Institution in Washington, D.C. This trophy perhaps symbolizes the hard work, dedication, and enthusiasm that were to be prevalent throughout all of Dr. Link’s remarkable life. Interestingly enough, this was the last balloon race in which Dr. Link competed. Aeronauts were considered daredevils at that time and Dr. Link did not want the balloon racing to affect his reputation as a surgeon.

In the mid 1930’s, Dr. Link purchased about 50+ acres in northern Morgan County in Indiana that was part of the Amick Apple Orchard, and he built a country home. At that time, this land was not in a residential area, but rather was located within a large logging region. He named this property Tanager Hill after the scarlet and summer tanager birds found in the area. As a widower at the age of 58 in 1937, he married his second wife, Helen, who was 25 years of age, and who had been his suture nurse at St. Vincent’s Hospital.

Dr. Link’s interest in astronomy also began at this time when he attended a series of lectures on astronomy given by I.U. at the Indianapolis Extension Center. On his honeymoon, he and Helen traveled out west to visit several of the western observatories. During this trip, they met with Russell Porter who had designed the Mount Palomar Observatory in California. Mr. Porter provided him with a drawing modeled after the Mt. Palomar Observatory so that he could build his own observatory when he returned to Indiana.

Dr. Link began construction on the observatory in 1937 with the assistance of the Indiana Astronomical Society (IAS) which was formed as an organization only four years earlier by Samuel Waters. Dr. Link acquired a 36-inch (0.91-meter) diameter Pyrex disk for the telescope’s primary mirror from the Corning Glass Works. This 400-lb honeycomb disk was a surplus test blank made for the historic Hale Observatory 200-inch mirror project located on Mt. Palomar. Ironically, Dr. Link finished building his observatory and telescope nine years before the telescope at the Hale Observatory saw first light. The mirror was ground using a custom made mirror-grinding machine that was designed and constructed with the assistance of IAS members. This grinding machine still resides in the storage shed on the observatory property. The telescope was made and assembled entirely in Indianapolis including having the massive mountings crafted by local machine shops. The telescope tube was constructed of a new aluminum alloy called Lynite, and it contained over 500 individual pieces that were drawn together by tension struts. In all, the telescope and its mounting weigh 5,000 lbs.

To support the telescope, a 200 ton concrete pier was required and the concrete for the above ground portion was poured in one shovel full at a time. The pier rests on bedrock 26 feet below ground level and extends 30 feet into the air. Instruments mounted on the pier showed that it dried to within 1 mm of its intended position. The all-wood building that surrounds, but does not touch the telescope and its pier, is made of massive oak posts and beams that were cut in the forest just a few miles away. The interior of the building is finished with hardwood floors, knotty-pine paneling, and beamed paneled ceilings. Rooms in the lower portion of the building include an auditorium, library, photographic darkroom, bunk room, basement, and kitchen. When the telescope saw its first light in 1939, only eight observatories in the United States possessed telescopes of equal or larger size. This is an impressive accomplishment for an amateur astronomer using only private funds.

The original plans for the building called for an all-metal dome, but the design was modified and only wood was used, but the dome’s exterior surface is sheathed in thin zinc panels. The 34-ft diameter dome weighs nearly 34-tons including the two shutters that weigh one-ton each. The shutters can be opened from side-to-side to provide a sky-viewing slit eight feet wide, and the dome can be rotated to various viewing positions using only a one-half horsepower motor. The flat roof over the auditorium originally supported a second, smaller dome that housed Dr. Link’s personal telescope - a 5-inch Zeiss refractor. The dome was removed in 1948 and can still be seen on the grounds across the parking lot from the main building. This telescope was used for several years, but was later moved to Bloomington campus, although its exact whereabouts remain a mystery. Currently, the smaller dome is not being used.

Dr. Link founded the observatory to advance astronomy in Indiana and specifically to benefit IAS members. He also offered use of the observatory to all the surrounding colleges and universities. DePauw, Butler and Indiana accepted his generous offer, but only Indiana was the only institution that had an astronomy department. I.U. took full advantage of this offer by creating the position of Research Fellow and hiring an astronomer, Dr. James Cuffey, to work full-time at the observatory. Soon after the observatory construction was completed, The Goethe & Helen Link Foundation for Scientific Research provided an endowment to maintain the observatory so that it could be used free of charge.

Although interest shifted away from the observatory during WWII, it again became the prime center for astronomy in Indiana after the war ended. There was strong interest in finding asteroids whose orbits had been lost because of the interruption of observations caused by the war, but the 36-inch telescope at Link Observatory was not suited for this task. An agreement was made between the University of Cincinnati, Indiana University, and Dr. Link to build a 10-inch astrographic telescope on the Link Observatory grounds to look for these asteroids. The University of Cincinnati agreed to “permanently” loan I.U. a 10-inch Cooke lens, I.U. offered to provide the funds to build the mounting, and Dr. Link agreed to pay for the building. Soon after this agreement was made, Dr. Link decided that it was becoming too much to maintain the observatory, so he offered to donate the observatory to any university in Indiana. I.U. was the only university in a position to take Dr. Link up on his offer, so the observatory along with 12-acres was donated to I.U. in 1948. The other portion of the property that included the Link’s country home was retained for the use of Dr. Link and his wife while they were still alive. The donation of the observatory enabled I.U. to significantly improve their astronomy department, and they immediately instituted a Ph.D. program in astronomy.

The 10-inch photographic (astrographic) telescope was completed in 1948 and is housed behind the main observatory building in a roll-off roof shelter that also contains a photographic dark room. The building plans and the Fecker telescope mounting for the 10-inch telescope were based on similar designs at the Leander McCormick Observatory at the University of Virginia. The 10-inch telescope was used from 1948 to 1967 to photograph the sky in search of asteroids, and ranked 2nd in the world in finding them. 6,267 glass photographic plates measuring 8 x 10 inches were exposed, and over 100 new asteroids (also called minor planets) were discovered. Glass transparencies of one of the asteroid photographs as well as photographs taken with the main 36-inch telescope are displayed in the auditorium as well as the pier room.

The original 36-inch telescope was a Newtonian design and required the observer to look through an eyepiece near the top of the telescope. Using rails attached to the dome, a six-person platform could be raised to reach the top of the telescope for viewing. The platform design was based on the same principle as one used at Steward Observatory at the University of Arizona. Public nights at Link Observatory were started in 1946 at Dr. Link’s request, and the observatory was opened up four Saturday nights in the fall and spring. On these nights, over 100 people would crowd into the auditorium for a presentation while an additional 100 people waited in line to be raised up on the platform to look through the telescope.

In 1966, the telescope was replaced with an updated design in order to carry heavier astronomical equipment such as photometry and spectrographic instruments. An investigation was made to see if a hole could be drilled through the center of the original mirror to make the telescope a true cassegrain design. It was feared, however, that drilling a hole would damage the mirror, so alternate plans were implemented and a bent-cassegrain design was used. Photoelectric photometry work required that the electronics be kept very cold for the best performance. A mechanical grinder can still be seen in the dome that was used to grind up dry ice for this purpose.

The last major update to the facility occurred in 1978 when a control room was built to better protect the equipment and the observer from the elements. Use of the telescopes by students and professional astronomers continued through the 1980’s when the light pollution from Indianapolis and nearby communities eventually made the sky at Link too bright for professional observing. Today, I.U. astronomers conduct their research with robotic telescopes closer to campus and at mountaintop observatories in Arizona, where more than 80 percent of the nights are clear.

Besides his interest in astronomy, Dr. Link also became an accomplished ornithologist and herpetologist. As an ornithologist, he developed a multi-station humming bird feeder that required over 60 pounds of sugar in solution during the summer feedings. His interest in herpetology started when he was looking to protect his youngest son, Goethe Jr., from the poisonous copperhead snakes that were known to inhabit the area around Tanager Hill. Although his research into how to eradicate copperhead snakes did not find any easy solutions, he did end up becoming one of the foremost experts on this type of poisonous snake.

Dr. Link passed away in 1981 at the age of 101 years. Some of his medical instruments can be seen in a display case in the observatory auditorium. His wife Helen continued to reside in their country home on Tanager Hill located near the observatory until she passed away in 2002 at the age of 90. She developed her interest in daffodils after Dr. Link gave her a bushel basket full of bulbs as a gift. Eventually, Mrs. Link became president of the International Daffodil Association, and her duties took her all over the world. At one time she had over 1100 different varieties of daffodils in flower beds spread over four acres, and her gardens are usually opened to visitors in the spring when they are in full bloom.

I.U. continues to own and maintain the Goethe Link Observatory. The Indiana Astronomical Society (IAS) currently uses the facility for the benefit of its members and the public. From May through October, the IAS has its General Meetings on the 2nd Saturday of those months. General meetings begin at 7:00 pm and usually include a guest speaker, and are held whether the sky is cloudy or clear. Observing sessions, held throughout the year, are convened on the Saturday closest to the new moon, but are held only held if the skies are clear. Visitors are welcome to any meeting, but it is recommended that they check the IAS website at www.iasindy.org to verify any change of plans. One can also call the observatory at 317-831-0668 to see that it is open.
