Bayer Logo: History, Meaning and Colors

Introduction

The Bayer logo — the Bayer Cross — is the emblem of German industrial science. Since 1863, Bayer has made aspirin, agriculture, and everything in between, and its green-and-blue cross is one of the oldest trademarks on Earth.

If you are searching for the Bayer logo, you are looking for the mark of Bayer AG, founded in 1863 in Leverkusen, Germany. This article traces the history of the Bayer Cross, explains its design, and breaks down the brand’s official colors.

Bayer Brand Overview

Friedrich Bayer founded Bayer in 1863 as a dyestuffs company. The company invented aspirin (1899, Felix Hoffmann), heroin (1898, infamously), and modern crop science (Monsanto, acquired 2018). 100,000+ employees across Pharmaceuticals, Consumer Health, and Crop Science.

History of the Bayer Cross

The Bayer Cross — “BAYER” written vertically and horizontally, intersecting — was designed in 1904 and registered as a trademark in 1914. The cross within a circle (green and blue) is one of the oldest continuously used trademarks in the world — 120 years of the same essential mark, refined for each era.

Bayer Logo Meaning: What Does the Cross Represent?

• The cross: Intersection — science meeting life, chemistry meeting care.
• Green: Life and agriculture — the crop science division’s color.
• Blue: Science and health — the pharma division’s color.
• 120 years: Endurance — one of the oldest trademarks on Earth.

Bayer Logo Colors

Bayer’s palette is science green and health blue.

Green is the field; blue is the lab — Bayer works in both.

Conclusion

The Bayer Cross is the logo of industrial science’s long game — a 1904 mark that’s still prescribing and planting in 2026. Aspirin’s cross, agriculture’s cross, in green and blue.
