Royal Eijsbouts

Royal Eijsbouts is a historic Dutch bell foundry based in Asten, North Brabant. Founded in 1872 by Bonaventura Eijsbouts as a workshop making tower clocks, the business gradually expanded into the manufacture and installation of striking and swinging bells, carillons, tower clocks, and related mechanical and musical systems. It remains associated principally with cast bells used in churches, carillons, civic buildings, and other architectural settings. The company’s development followed the growing popularity of carillons in the Netherlands and elsewhere. In 1893, Bonaventura’s teenage son Johan joined the workshop. Johan broadened the business by obtaining bells from established English foundries, including John Taylor Bellfounders and Gillett & Johnston, and incorporating them into carillons supplied or installed by Eijsbouts. This period established the company as more than a clockmaker: it became an integrator of timekeeping, bell casting, musical programming, and architectural installation. A major technical turning point came with the arrival of Johan’s eldest son, Tuur Eijsbouts, in 1924. Interested in the metallurgy, acoustics, and engineering of bells, Tuur pursued the knowledge required to cast bells in-house rather than relying on external suppliers. After years of experimentation, Eijsbouts installed its own bell foundry in 1947. This allowed the company to control the design, casting, tuning, finishing, and installation of its bells and helped establish the technical identity it retains today. Royal Eijsbouts combines traditional foundry practice with research into campanology, the scientific and musical study of bells. Its research has supported computer-based methods for calculating bell shape and sound characteristics. The company has also worked on specialized tonal designs, including a major-third bell whose harmonic structure is intended to reproduce the character of a traditional bell while using a major rather than minor third above the fundamental. The company’s work extends beyond standard church bells and carillons. It makes custom tower clocks and astronomical clocks in a range of sizes and operates an art foundry capable of casting sculptures, statues, and other commissioned works. Its projects may therefore involve architectural conservation, public art, civic timekeeping, religious heritage, and musical instrument construction. Among its notable commissions was the production of Marie, the largest bell in the renewed bell set for Notre-Dame Cathedral in Paris. Royal Eijsbouts cast the approximately six-ton bell in Asten in 2012 as part of preparations for the cathedral’s 850th anniversary. The bell was subsequently transported to Paris, dedicated with the other new bells in 2013, and installed in the cathedral’s belfries. In 2014, Royal Eijsbouts acquired Petit & Fritsen, another Dutch bell foundry based in Aarle-Rixtel. Foundry activity at the acquired site was later ended and transferred to Asten, consolidating Dutch production within the Royal Eijsbouts operation. The company continues to present itself as an active specialist in bells, carillons, clocks, campanological engineering, and artistic casting.

Royal Eijsbouts traces its origins to 1872, when Bonaventura Eijsbouts established a workshop in Asten for making tower clocks. The early business focused on clock manufacture and related installation work. In 1893, his son Johan joined the workshop at the age of fifteen. Under Johan’s involvement, the company began supplying striking and swinging bells alongside its clocks, initially sourcing the bells from other foundries. The spread of carillons created a new opportunity. Johan purchased bells from English specialists John Taylor Bellfounders and Gillett & Johnston and used them in carillons that Eijsbouts supplied or installed. This broadened the company’s role from clockmaker to provider of integrated bell, clock, and carillon systems. In 1924, Johan’s eldest son, Tuur Eijsbouts, entered the business. Tuur concentrated on the technical problems of bell manufacture and began learning how to cast bells himself. Following years of experimentation, the company established an in-house bell foundry in 1947. Internal casting gave Eijsbouts greater control over bell profiles, metallurgy, tuning, finishing, and installation. The company subsequently became known for bells used in church towers and carillons. Its activities were supported by continuing research into campanology, combining the musical study of bells with engineering and acoustic analysis. This work led to computer applications intended to calculate bell geometry and sound characteristics, as well as specialized products such as a major-tierce bell designed around a major-third relationship while retaining the harmonic character associated with traditional bells. Royal Eijsbouts also expanded its scope through custom-made tower clocks, astronomical clocks, and artistic casting. The art-foundry operation produces sculptures and statues using multiple casting techniques, allowing the company to serve architectural, civic, religious, musical, conservation, and public-art commissions. A prominent modern commission came from the restoration and renewal of the bells of Notre-Dame Cathedral in Paris. In connection with the cathedral’s 850th anniversary, Royal Eijsbouts cast the approximately six-ton Marie bell in Asten on 14 September 2012. The bell was transported to Paris, dedicated with the other new bells in February 2013, and installed in the cathedral before the restored set was heard publicly in March. In 2014, Royal Eijsbouts acquired Petit & Fritsen, its last Dutch competitor in bell founding. The acquired company was based in Aarle-Rixtel, but foundry operations there were later terminated and transferred to Asten. Royal Eijsbouts remains an active specialist manufacturer whose work combines historic craft methods, acoustic research, custom engineering, and architectural installation.
