324:. The expansion into the United States was met with difficulties. Koenig's expectations for the expansion of his business were not working as he had hoped. He did have some help from his customers, but was not pleased with the results. This led to Koenig having to travel to America in order to retrieve his leftover products and bring them back. It was decided to no longer take part in the exhibition. Following all of this he decided to start doing more of his own research, and also began to write many scientific articles while improving upon his instruments. In 1882 Koenig published

Two years following this in 1862, he began to exhibit the nano-metric flame apparatus (see attached image and description for more information) at the

In 1865, Koenig published his second catalog, and was awarded a gold medal from the
Societe d'Encouragement pOllr l'lndustrie ntuionale for the use of his instruments in working with the study of acoustics .In 1867, his apparatus collection was exhibited in Paris. After few exhibitions, many of

Rudolph Koenig was known to be a great craftsman, but a lesser known interest of his was physics. Sounds in particular were a fascination of his, to the point that he spent a large amount of time and money doing research on acoustics. Early on in life, he took a position as an apprentice in the

The business started in his apartment which consisted of a living room, bedroom, and a workshop along with the laboratory. It was a small and quiet place where Koenig worked with his passion of acoustics and music. He would spend most of his free time and money on this same passion. In 1861, Koenig

Rudolph had little education past high school. He attended primary school and had the usual high school at gymnasium. The extent of his formal education was completed in his hometown where his father was among the faculty. Early on it was clear that
Rudolph had a keen ear for music and a good sense

In 1859, Koenig both published his first catalog, and inverted the phonograph which would play a crucial role for the graphical analysis of sound. By inverting the phonograph, Rudolph made it easier to record and store sounds made by the vibrations of air particles. Around 1860, along with

The business employed about three workers, however Koenig made almost all of his own instruments. Koenig was a meticulous worker and personally checked and tuned every instrument that was produced. He was well known in his time to make near perfect instrumentation of high quality.

One of Koenig's more interesting devices was a watch with the escapement consisting of a tuning fork that could calibrate the main frequencies of any sound. This apparatus helped Koenig establish the frequencies of musical tones and allowed him to build a musical scale.

Rudolph Koenig produced a variety of devices and acoustic instruments. These devices and instruments include a sound analyzer, tuning forks, double risen, wave machines, resonators, devices for sound visualization, and obtaining ultrasonic frequencies etc.
291:
In the late 1800s Koenig found out that people were making cheap copies of his acoustical apparatus. He complained about these knock off instruments, stating that some even had his name on them despite the fact that he had nothing to do with their creation.
283:
Another apparatus was a phonograph which could collect sounds by means of a pavilion. It could automatically record them in a rotating cylinder by means of a point. Some years later, Thomas Edison developed this device to build the
Phonograph known today.

Among many other products, Koenig also built measuring instruments which were composed of resonators. He also authored various works on limits of hearing, the physical characterization of vowels and the combination of tones.

Koenig's manometric flame apparatus (1862), used to visualize sound waves. Air pressure from an acoustic phone altered the flame provided by a Bunsen gas flame, which was amplified by a rotating mirror and
