Gemeinhardt Co. is a manufacturer of flutes and piccolos. These musical instruments are developed by this company for all levels of musicians, beginners to professionals. Gemeinhardt was owned by Angel Industries Co. Ltd of Taiwan, widely acknowledged as a premier manufacturer of woodwind musical instruments. The Gemeinhardt Company is headquartered in Elkhart, Indiana, where many of its instruments are still made. Gemeinhardt Musical Instruments was purchased at the end of 2024 by Ramon Noguera of Raynog Ventures (which also owns Laconia Music in New York).

From 1993 to 2011, Gemeinhardt was owned by investment bankers under the corporate name Gemstone Musical Instruments. In June 2011, Gemeinhardt was acquired by Angel Industries Co. Ltd. of Taiwan, musical instrument manufacturers and business partner of Gemeinhardt for several years. David Pirtle, Gemeinhardt president and CEO, said the acquisition would allow Gemeinhardt more freedom to make decisions and run production in order to best serve the market.

While many musical instrument brands are manufactured overseas, the partnership between Gemeinhardt and Angel Industries is unique. Gemeinhardt manufactures flute components (headjoint, body, footjoint, keys) in Elkhart, Indiana, then sends them to Angel for assembly. The assembled instruments are returned to Elkhart for testing and adjusting in the Gemeinhardt workshop. While most musical instrument brands have flute components manufactured overseas, Pirtle said Gemeinhardt's method is preferable because better quality flute parts can be made in their U.S. workshop.

Fourth-generation flute maker Kurt Gemeinhardt was brought to the United States from Markneukirchen, Germany, by George Bundy of Selmer USA which had recently relocated to Elkhart, Indiana. Working with Philip H. Marcil in the Selmer flute division, they copied the typical Louis Lot design for their flutes.

Kurt's father had studied under Emil Rittershausen, who was trained by Theobald Boehm; thus, the instruments Gemeinhardt produces can trace their lineage to the creator of the Boehm system.

In 1948, twenty years after Gemeinhardt immigrated, he founded the Kurt Gemeinhardt Company. Initially, the company crafted only very fine handmade flutes for professionals. However, the company moved to Elkhart and expanded in 1952, producing all levels of silver flutes. Beginner student flutes were also developed at this time; as Gemeinhardt’s reputation for fine beginner flutes became a hallmark of the industry, these flutes eventually became the bread and butter of the corporation.

The Gemeinhardt Company is very popular in the music field, although they have not always followed the mainstream. In the mid '70s, Albert Cooper modified the placement of toneholes on the flute so it would match the common tuning of A at 440 Hz. Before this, many flutes were made with an older A435Hz tone hole placement (scale), despite being designed to play at A440Hz through the use of a shortened headjoint.

Many flute companies recognized this change and decided to make their flutes the same way, but Gemeinhardt was slow to modify its design. This in turn made notes played in the higher register on an old Gemeinhardt flute sharp and the lower register flat, which could cause issues for beginner flautists using an old Gemeinhardt (pre-21st century). With practice, they could learn to play so the notes are correct, or they could consider buying a newer Gemeinhardt.
