Early Life and Background
Hermine Poitou was born and raised in France, a country known for its rich artistic culture and history. Growing up in such an environment inspired her to pursue a life in art and design. From an early age, she showed a natural interest in drawing, color, and visual storytelling. The cultural influence of France — from its architecture to its visual arts — shaped her creative vision and helped her appreciate beauty in simplicity. Although Poitou has kept details about her childhood and family private, her later accomplishments reflect a deep appreciation for European art traditions. Unlike many artists who seek fame, she values authenticity and introspection, which is evident in both her lifestyle and her work. Her early years in France gave her the foundation for her minimalist approach, blending structure with emotion — a theme that runs throughout her entire artistic career.
Education and Artistic Training
Hermine Poitou’s education was central to developing her creative identity. She began her formal training at Aix-Marseille University in France, where she studied Arts Plastiques and earned a DEUG degree between 1986 and 1989. This period allowed her to explore fine art principles and build a strong academic foundation. She then sought to expand her horizons internationally and moved to the United Kingdom for further studies. At Newcastle College of Art & Design (1990–1992), she completed a BTEC in Graphic Design, learning the technical side of visual communication. Her most defining academic experience came at Camberwell College of Arts in London (1992–1996), one of the UK’s most prestigious art schools. There, she earned joint honors in Graphic Design and Fine Arts. This blend of French artistic theory and British design practice shaped her unique cross-cultural style — refined, minimalist, and deeply thoughtful. Her time in London introduced her to modernist design concepts, which she later combined with her French sensibility to develop a timeless visual language.

After completing her studies, Hermine Poitou entered the professional world of design with impressive determination. Her first role was at Textuel, a communication agency in France, where she worked as a graphic designer and illustrator from 1997 to 1998.

She later joined BDDP & TBWA Interactive between 1998 and 2000, serving as an art director, where she managed digital and print campaigns for several well-known brands. These early experiences provided her with valuable insights into advertising, branding, and visual storytelling.

Since then, she has collaborated with clients in publishing, advertising, and visual identity design. Her work stands out for its clean lines, balanced compositions, and subtle modernist influences. Beyond commercial projects, she also contributed to the film industry, creating casting graphics for movies such as Russian Dolls (2005) and A Child’s Secret (2006).
