Dr. L. E. Custer:  Dedicated to His Profession

By E. J. Spencer, D.D.S.


                The dentist who brought most plaudits to Dayton in the profession is best known for his inventions and is fondly remembered as the spark plug of any meeting in which he had a hand.

                Like all great individuals, Dr. Levitt Ellsworth Custer had some underlying philosophies which would serve any dentist well today, just as they served him more than seven decades ago.

                He often said he observed the fundamental principle in any enterprise—“strict attention to business.”

                This from a man who kept waiting patients in fear of sitting down in his office where he combined his electrical knowledge and interest in devices that were literally shocking more often than not.

                This from a man who usually had his cornet at hand when he attended dental association meetings the country over and liked nothing better than to parade up and down the hotel halls in the wee hours blaring “There’ll be a Hot Time in the Old Town Tonight.”

                This from a man who invented a porcelain oven that was to enable any dentist to make porcelain fillings and crowns, a process which had previously been limited to less than a dozen dentists the world over.

                Dr. Custer worked hard whether in his electrical shop, his dental office, backing a civic endeavor, playing in a band or ballooning.  The latter was to become his major recreation, but even his desire to escape daily chores did not stop his genius.  He invented a wireless device for control of dirigible balloons and torpedo boats.

                Dr. Custer was born June 18, 1863, at Perrysville, Ohio.  His father, Isaac Newton Custer, was a dentist. He attended public schools in New Philadelphia and Westerville before entering Otterbein University, from which he was graduated in 1884.

                As a youngster, he worked for a jeweler and in his father’s dental office.  His savings for his college training came from a year (1878-79) he spent playing cornet with a river circus band traveling from Cincinnati to New Orleans.  Before entering the Ohio College of Dental Surgery in 1885, he taught music and school at the Boys’ Industrial Farm at Lancaster.

                As he completed his junior year at dental school, a written examination was required for the first time.  Custer’s paper so pleased the faculty that he was given a scholarship for the next year, thus inaugurating the gift of a junior prize for the best general examination.

                At graduation, he received two gold medals, one for the best general examination and the other for best attainments in mechanical dentistry.  He also received first honorable mention in operative dentistry.

                But Dr. Custer’s success rate was not 100 per cent.

                He once told Dr. Burton Lee Thorpe, who had asked him for the essentials for success in young men in dentistry.  “I began the practice of dentistry n Springfield, Ohio, in 1887, with meager equipment.  Spent my spare moments, of which I had many at first, in making an electric engine and other appliances, which I am still using today.  I would have located in Dayton form the beginning, as that was my preference, but a dentist by the name of Elson, having heard of my attainments at the dental college, offered me a partnership, the conditions of which I could not accepts.  In the fall of the same year he prevailed upon me to enter partnership in Dayton, which I did in January, 1888.  I soon found him to be of the quack type and immediately took steps to sever this association with him and start up for myself.  The larger part of his practice had been shifted upon me and when I left him in August, 1888, the majority of these patients followed me, and from that day to his I have been busy every minute.  It’s an ill wind that blows nobody good.”

                But he also told Dr. Thorpe, “I always felt that I would have succeeded in any location for I observed the fundamental principle in any enterprise, namely, strict attention to business.  This included keeping up to date the literature of the profession, attendance at the dental association, and acquaintance with all things professional which would be of the greatest benefit to my patients.  I was continually studying and experimenting with electricity at all odd moments.  My fees have increased with my experience.”

                There’s nothing wrong with that advice and rewards are the same for today’s dentists or young men pursuing any endeavor.

                “I always paid a great deal of attention to the best means of saving all teeth and became known as a dentist who does not extract teeth.  The people of this city had to be taught that ‘ulcerated’ teeth could be saved.  If I had to choose my career again, I would not select the practice of dentistry today as a remunerative profession, however, but if I were about to begin practice again, I do not know of anything that I would do differently from what I have done.  The principal points a young dentist should observe in order to build and maintain an ethical practice and win the esteem of his community is to pay close attention to his profession, choose clean associates and live within his income.  Attend dental societies and keep busy either in his laboratory or with the literature of his profession.”

                It was his combination of dental dedication and a keen interest in electrical devices that was to make Dr. Custer best known in his profession.  Of all his inventions his electrical porcelain furnace was probably his formost.

                Until Dr. Custer introduced an oven in 1894 that would permit fusing of dental porcelain under careful control, less than a dozen dentists in the world used this type filling.  Previous methods called for a coal or coke oven, about the size of a medium sized book case, which required sex to eight hours of stoking before it was ready for use.  Then—and this was what limited the field of practitioners—care had to be taken to avoid ‘gassing’ the porcelain and to maintain temperature control that assured durability of the filling material.

                Dr. Custer’s oven, on the other hand, was about the size of a single book and brought about a purity of heat and perfect control.  Prosthetic dentistry was revolutionized.

                The first invention by Dr. Custer to win wide use among dentists was the first electric gold annealer, produced in 1890.  Previously, dentists passed gold through the flame of a spirit lamp to make it annealable.

                In 1893, Dr. Custer introduced a carbon arc light that brought the dentist 6000 degrees of heat so he could melt and work with platinum.  Before this invention, only refineries were able to obtain the temperatures of 3600 degrees necessary to salvage platinum scrap.  This method is expensive for the individual dentist. 

                Also credited to Dr. Custer’s inventive ability was the first electric cabinet, the first electric match, a right angle handpiece, a celluloid and chamois disc (this was bought by the S.S. White Company), an electric warm water device, an electric casting device and an interrupter for X-ray.

                 His keen interest in electricity brought him a fine library of books on the subject.  And he contributed much to scientific literature.  His textbooks, papers and recorded addresses totaled 46 before 1910, according to a bibliography published by the Dental Summary.

                Dr. O. B. Kneisly, in articles in the April and June, 1952, bulletins of the Dayton Dental Society, gave thanks for having had an opportunity to learn many of Dr. Custer’s dental methods using electrical appliances.

                Dr. Kneisly also wrote of Custer’s assistance to other dentists.  “To the young practitioner who was lucky enough to come under his observation, and who could take his gibes and tricks, he was a father confessor who would help solve difficulties and cheer the lagging heart when the going was rough.”

                Those tricks to which Dr. Kneisly alluded were legend.  Dr. Custer had his office filled with mechanical contrivances with electric motors seemingly everywhere.  Ceilings, walls and cases of drawers were loaded with gadgets of every kind.


“Touch Anything and You Dropped It Quickly—If Possible…”


                Not all were for the patients’ comfort, exactly.  Many a patient would never sit down in the anteroom again after being exposed to one of Dr. Custer’s “hot” seats.  “Sit down and you rose again promptly,” Dr. Kneisly related, “touch anything and you dropped it quickly—if possible…”  Once a person had fallen for one of his satanic pranks, Dr. Custer would roar with laughter and refer the “victim” to “that sign on the wall.”  Then the person would read the sign he had not noticed before, “Stand. Touch Nothing.”  The sign went unnoticed because it was above the door frame, seven feet from the floor.

                Custer’s friends knew him as “Lizzie.”  While he and most colleagues referred to him by that nickname, Dr. Kneisly said that they never learned why nor what it meant.

                As a musician, prankster, or just a jolly fellow, Dr. Custer brought much gaiety to dental meetings, especially those of the Ohio Society.  There are still many men who met him as the prime promoter and active officer of the Mystic Order of the Fleas.  For a quarter of a century, that organization flourished with only a hotel bathroom as headquarters and meeting place.  Ritualistic work, it was recalled, took place at the “altar,” and initiations were said to result in “quite a stink.”  No doubt fortunately, there was no book to outline obligations, so details cannot be reported since they we3re the secret of the only active officer the Mystic Order of the Fleas ever had.


Cloud Chasing Was Dr. Custer’s Hobby


                Dr. Custer’s real hobby was ballooning, or “cloud chasing” as it sometimes was called.  He was involved in owning a operating several balloons, the largest of which would carry five passengers.  Often Dr. Custer and another dentist with a similar interest, Dr. Plinney Crume, sailed balloons over the Dayton area, taking off from the Miami river bank near the Dayton Gas Company works,  Gas for the balloons was piped from the nearby works.



Custer’s Son Was Also an Inventor


                Dr. Custer had one son, Levitt Luzerne, who also had an interest in ballooning and became an early aviation fan with Dayton’s Wright brothers.  The son, who died in 1962, was also an inventor.  He developed vehicles for handicapped persons and amusement park devices.  The son also flew the balloon in which a small printing press was mounted, small size copies of the Dayton Journal were printed and then “distributed” as the balloon flew from Dayton to Indiana.  They carried mail on that flight in 1906, which was posted after they touched down in Indiana—probably the first instance of air mail.

                Dr. Custer died January 3, 1924, leaving his wife, Effie Zimmerman Custer, and his son.  Representatives of national and state dental associations attended his funeral in Dayton.


Custer Member of First Dental Board


                Dr. Custer did not shirk any political responsibility in his profession.  In 1892, Governor William McKinley appointed the first Ohio State Dental Board, and Dr. Custer was named a member along with Drs. Grant Molyneaux, J. E. Silcott, Grant Mitchell and Clare Smith.

                He was elected president of the Ohio State Dental Association in 1896, the first Daytonian to be so honored by the state society.  He was president of the Dayton Dental Society for the 1916-17 term.

                When the Annual Clinic Meeting of the State Association was held in 1955 in Dayton, Dr. Wilbur Adair, Chairman of the State Museum and History Committee, collected and restored many of Dr. Custer’s original inventions, working models and devices for a display.  After the meeting, the entire exhibit was presented to the Museum at Bainbridge , Ohio.

                Earlier, through the efforts of Dr. Kneisly and Dr. Ed Mills, Dr. Custer’s library had been given to the State Association’s library.

                Dr. Custer’s contributions to the dental profession are to be found in most any practitioner’s office even today, a century after his first and decades after his death.  And there are still many dentists living who learned professional lessons firsthand from the son of a dentist who combined all his energies into furthering the profession.
