Barometers Realm

This brass baroque-ornamented desk barometer from the second half of the 19th century, cast by the renowned foundry Ferdinand Killmer in collaboration with German manufacturer Emil Lessing**, is a true work of art, where symbolism, craftsmanship, and the aesthetics of the era merge into a single masterpiece. The barometer case is made of bronze and mounted on a stone base.

** There are assumptions that the presented mechanism was manufactured by Emil Lessing in Hamburg, while Braukmann registered it under his own name.

At the heart of the composition is a circular frame housing the barometer, upheld by two figures of Roman warriors. Their armor and distinctive crested helmets evoke the grandeur of the Roman Empire, symbolizing strength, discipline, and authority—reinforcing the notion of mankind’s attempt to harness and predict natural forces. At the base, reclining horses introduce a sense of stability and monumentality, counterbalancing the dynamic energy of the composition.

Rising above the frame is a slender spire, a direct reference to the heavens and atmosphere, underscoring the barometer’s function. Beneath the spire perches a double-headed eagle, its heads turned outward. This emblem signifies power, vigilance, and the unity of two realms—earthly and celestial—emphasizing the significance of knowledge and the observation of nature.

The designer of the barometer movement is Emil Lessing—a small German manufacturer of unusually shaped and styled aneroid barometer mechanisms. Inside the aneroid capsule, a helical spring is positioned at the center, which is why we do not see the characteristic external springs typical of aneroids. Another distinctive feature of the mechanism is the absence of a chain connecting the lever to the indicator component—instead, a thin twisted thread is used.

The barometer’s dial is crafted from carton board, upon which the barometric scale is inscribed in centimeters of mercury, accompanied by a standard weather indication in Dutch, written in uppercase letters. Through the open dial, a breathtaking view of the intricate internal movement unfolds. The eye is drawn into the depths of the mechanism, tracing the path along exquisitely crafted brass components until it meets the golden aneroid capsule at the core.

To protect the dial, a beveled glass cover is set within a brass bezel, which is securely fastened to the barometer’s body with screws.

Foundry logo

The manufactory hallmark of FERDINAND KILLMER, located on the back surface, takes the form of a circular emblem, where symbols are meticulously arranged to reflect the philosophy and values of the maker. At its center lies a spoked wheel, a powerful representation of movement, progress, and artisanal craftsmanship. Near the left spoke, elements resembling flames can be discerned—an embodiment of energy and the dynamic nature of the manufacturing process.

Above the wheel, an anvil and hammer intersect, signifying the importance of manual labor and the force of creation. Just below, gracefully draped fabric bears the Latin motto "Carpe Diem"—"Seize the moment." This inscription not only underscores the significance of action in the present but also highlights the value of cherishing the fruits of one's labor. A handcrafted piece is not merely a utilitarian object but a work of art, deserving of admiration.

In the lower section of the circle, the Masonic compass and square are depicted—timeless symbols of the Freemason’s journey, shaping raw stone into refined form. The square represents Earth, while the compass symbolizes the Heavens, encapsulating ideals of integrity, harmony, and the pursuit of perfection.

Encircling the emblem, the name of the manufactory, "FERD: KILLMER", is inscribed, marking the piece as the creation of a specific foundry. Below it, the serial number "14031" serves as a unique identifier of the product.

This hallmark embodies a delicate balance between craftsmanship, philosophy, and art, uniting the symbolism of artisanal mastery, creative energy, and the joy of accomplishment.

Ferdinand Killmer

Ferdinand Killmer was a court jeweler (Hofgoldschmied) and sculptor who lived and worked in Hanau am Main(Hesse) in the 19th century. His craftsmanship and artistic vision were recognized far beyond the borders of Hanau. Killmer specialized in metalwork, including fine jewelry and likely other forms of decorative arts.

He received his education at the Hanau Academy of Arts, where he was awarded a first-class copper medal for his outstanding achievements. This prestigious academy was renowned for its commitment to merging art and industry, which may have influenced Killmer’s specialization in jewelry and applied arts. In addition to his own artistic work, he also trained students in his workshop, passing down his expertise to the next generation. Killmer adopted one of his apprentices, who inherited his studio after the master’s passing and continued his craft. This suggests that Killmer’s workshop functioned not only as a center of production but also as a training institution, fostering tradition and nurturing new talent.

Ferdinand Killmer was married, and his only daughter, Elsbeth Killmer (1890–1957), became a painter and sculptor. She received her early artistic education under her father’s guidance, who encouraged her talent from a young age. She later continued her studies in the academic circles of Frankfurt am Main and Munich.

His contributions to art and education helped preserve the legacy of the Hanau school of arts, strengthening the connection between fine arts and the jewelry industry in the region.
