Claudia Hartmann

Claudia moved to Shanghai for seven years followed by another four years in Singapore where she was exposed to diverse cultures that pushed her to return to oil painting with a new vision.

In 2006, she returned to Ticino/Switzerland, where she was introduced to sculpturing, influenced by the artist Gianmarco Torriani, a passion that led her on a constant path of growth both stylistically and personally. Since then, she has deepened her knowledge, experimenting with sculpture on marble in the Arzo caves. She further perfected her craft at the Perseo foundry in Mendrisio, Switzerland. 

Claudia Hartmann is known for her vibrant biomorphic art sculptures, inspired by organic, living, and natural forms (such as cells, plants, and marine organisms), characterized by curves, fluidity, and complexity, distinguishing them from rigid geometric forms. Her works, though made of bronze, evoke lightness, movement, and a sense of natural mystery, inviting the viewer to slow, sensorial contemplation. Her practice combines a material sensitivity with a contemporary formal language, enriching the artistic landscape with unique pieces that blend nature and abstraction.

Hartmann’s sculptures strongly evoke the golden spiral of Leonardo Fibonacci. The Fibonacci sequence is a numerical series (0, 1, 1, 2, 3, 5, 8, 13, 21, …) in which each number is the sum of the two preceding ones.

By constructing squares with sides equal to Fibonacci numbers and drawing an arc within them, one obtains the golden spiral, which is common in nature (sunflowers, pinecones, nautilus shells, galaxies, etc.).

Dividing a number in the sequence by the previous one (e.g., 55/34, 89/55) yields a result that increasingly approaches 1.618, known as the golden ratio.

By incorporating these sequences into his works, Hartmann creates sculptures with highly harmonious proportions that instinctively and naturally stimulate the senses of those who observe them. The surface finish of the works, with colored patinas ranging from classic brown tones to blues and reds, ignites the pieces with a warm and refined brilliance. The vibrant movement of the lamellae and fibrils, a characteristic feature of Hartmann’s work, has a pleasant tactile quality, inspiring the desire to caress their surfaces.
