The Siemens logo is one of the longest-standing visual identities in European industry, a symbol that has evolved slowly and deliberately as the company expanded from a small Berlin workshop into a global technological force. Although the modern emblem is a simple turquoise wordmark, the brand’s visual heritage stretches back to the 19th century, when Siemens relied on ornate monograms and industrial symbolism to express its identity.

This is the complete story of the Siemens logo — its meaning, symbolism, and evolution.

Meaning & Symbolism

Siemens built its identity on precision, engineering excellence and modernity, and each iteration of its logo has reflected these values. The earliest monograms symbolized partnership and craftsmanship, combining the initials of founders Werner von Siemens and Johann Georg Halske. As the company matured, the logo shifted toward minimalism and industrial clarity.

Today’s turquoise wordmark symbolizes reliability, safety and forward-thinking innovation, while maintaining the seriousness and authority that have always defined the Siemens brand.

Siemens Logo Evolution Through the Years

1847–1899: The Early Monogram

The company’s first emblem was a simple monogram built from the initials of Siemens and Halske. The “H” featured angled uprights that almost formed an “X”, while the “S” was positioned symmetrically in the center. The black color gave the mark a formal, almost architectural presence. This design became the foundation for all future versions.

1899–1925: The Interlaced SH Symbol

At the turn of the century, Siemens introduced a new interpretation of the monogram. The “S” grew more elongated and wrapped around a compact diagonal “H”, forming a distinctive geometric figure that became instantly recognizable. It conveyed industrial strength during a period of rapid expansion.

1925–1928: The Circle Emblem

The monogram was placed inside a circular border, creating a compact and well-balanced mark. The thickness of the circle matched the weight of the letters, giving the symbol a disciplined, engineered appearance appropriate for a company deeply involved in electrification and communications technology.

1928–1936: The Framed Badge

Siemens refined the emblem again by adding an outer pentagon frame around the circle. For the first time, the name SIEMENS appeared beneath the symbol in clean capital letters. The combination of geometric frames and typography conveyed stability, authority and modern engineering.

1936–1973: The Clean Industrial Layout

The frames disappeared entirely, leaving the SH monogram positioned above the Siemens name in a simple, modern sans-serif typeface. The spacing between the letters increased, giving the wordmark an airier appearance. This version remained in use for nearly four decades, marking Siemens’ transition into a global industrial leader.

1936–1991: The Wordmark Takes Over

In parallel with the monogram version, Siemens also used a standalone wordmark. The bold, geometric sans-serif lettering projected confidence and technical expertise. Over time, this minimalist version became more prominent than the historic SH symbol, hinting at the direction Siemens would take.

1991–Today: The Modern Turquoise Identity

The monogram was finally retired, and Siemens introduced its clean turquoise wordmark — a design that has remained unchanged for more than three decades. The custom sans-serif letters, similar to Dialog Pro Extra Bold or Lucida Grande Black, were refined to look crisp and contemporary.

The new color, a fresh shade of turquoise, became a defining element of the brand. It expresses trust, reliability and clarity, while marking a definitive shift into the modern digital era.

Font

Color

The signature Siemens turquoise, introduced in 1991, reflects clarity, calmness and technological confidence. Earlier logos were strictly black-and-white, aligning with the industrial design standards of the time.
