Farbenfabriken Bayer AG was the corporate name used by the German chemical and pharmaceutical company Bayer during much of the 20th century. The identity associated with this name is the Bayer Cross, a trademark registered on January 6, 1904, that has remained the company’s core visual symbol for over a century.[1]
Design and History
The Bayer Cross originated around 1900, though the company’s archives contain two competing accounts of its creation. One version credits Hans Schneider, an employee in the Scientific Department in Elberfeld, who reportedly wrote the word “Bayer” horizontally and then vertically on a piece of paper, producing the cross form. The other attributes the design to Dr. Schweizer, who worked in Bayer’s New York office in the 1890s and developed the cross as a memorable company stamp to overcome the difficulty of communicating the firm’s long name, Farbenfabriken vormals Friedr. Bayer & Co., Elberfeld.[1]The cross replaced an earlier heraldic lion emblem. When Bayer received its first German patent in 1881, it adopted a trademark based on the coat of arms of Elberfeld, where the company was headquartered: a two-tailed lion holding the grid on which Saint Lawrence, the town’s patron, was martyred. This symbol was modified in 1895 into a winged lion holding a caduceus and standing over a globe. The Bayer Cross gradually displaced the lion in Europe and was used exclusively by Bayer’s overseas offices from early on.[1]The trademark was first updated in 1929, when the previously slightly italicized letters were straightened.[1] A Taiwanese trademark record shows that a Bayer wordmark application was filed on August 3, 1965, under the name “拜耳ＢＡＹＥＲ” (Bayer BAYER), registered on May 1, 1966.[2] However, no official Bayer source documents a 1965 redesign of the corporate logo by Graphicteam Köln or any other agency. The claim that the Farbenfabriken Bayer AG symbol was designed at Graphicteam Köln in 1965 appears only in unverified logo databases and cannot be confirmed by primary sources.[3]In 2002, the cross received its first colored version, rendered in the company colors of blue and green, intended to symbolize Bayer’s modernity and freshness.[1] After a modification in 2010, the Bayer Cross was slightly redesigned again in 2017, with color gradients in the circle removed and colors adjusted for better use in digital media.[1]Meaning and Symbolism
The Bayer Cross was registered in 1904 for use on “medications for people and animals, disinfectants, preservatives, tar dyes, and chemical preparations for dyeing and photographic purposes,” and since 1914 it has also been used for crop protection products.[1] From 1910, the logo was stamped on tablets, particularly Aspirin, protecting pharmaceutical products from counterfeiting and becoming familiar to consumers as a symbol of premium quality.[1]The cross also became a physical landmark. In 1933, a 72-meter illuminated Bayer Cross with 2,200 electric bulbs was installed between two smokestacks at the Leverkusen site, described by the Bergische Post newspaper as the “world’s largest illuminated advertisement.” A second, smaller cross with a 51-meter diameter was inaugurated in 1958 and remains the largest trademark in the world.[1]Typography and Design
The Bayer Cross is constructed from the word “BAYER” written in capital letters, arranged so that the horizontal and vertical readings share the letter Y at the center. The original letters were slightly italicized until the 1929 update straightened them.[1] The 2017 redesign removed color gradients from the circle and introduced clearly defined lines, making the logo better suited for digital applications.[1]Logo Index is an independent educational archive covering logos, visual identities and graphic design history.
