Logo Evolution

The Bayer logo, an enduring icon of corporate identity, reflects the company’s evolution while maintaining its core values of innovation and trust.

1881 – 1886

The first Bayer logo featured a lion, drawn from the coat of arms of Elberfeld, Bayer’s original headquarters.

1886 – 1895

This design expanded into a complex emblem with illustrative elements like foliage and heraldic motifs, symbolizing tradition and strength.

1895 – 1904

Simplified to a winged lion gripping a globe and a caduceus, this version emphasized Bayer’s focus on medicine and its global aspirations.

1904 – 1928

The iconic Bayer Cross was introduced, featuring the name “BAYER” intersecting vertically and horizontally within a circle. Stamped on products like Aspirin tablets, it became a hallmark of quality and authenticity.

1929 – 1989

This minimalist cross design served as the foundation for modern Bayer emblems, consistently reinforcing brand recognition.

1989 – 2002

The logo adopted a more contemporary look, pairing the cross with a clean sans-serif wordmark and introducing Bayer’s signature green and blue color palette.

2002 – 2010

The cross was updated with gradients in green and blue, adding depth and a sense of freshness.

2010 – 2017

Gradients were toned down, and the letters became dark gray, reflecting simplicity and professionalism.

2017 – Today

The current logo features flat design aesthetics, eliminating gradients for a streamlined and modern look suitable for digital media.

Font and Colors

The Bayer logo uses a modern sans-serif font akin to Bristone Bold or Tapas Sans, conveying clarity and professionalism. The color palette combines bright green and blue, symbolizing growth, innovation, and wellbeing, with dark blue lettering signifying reliability and expertise.

Bayer’s visual identity aligns seamlessly with its reputation as a global leader in pharmaceuticals and agriculture, embodying its values of innovation, quality, and progress.
