Merck is a name shared by two distinct companies: Merck KGaA, the German science and technology company headquartered in Darmstadt, and Merck & Co., Inc. (known as MSD outside the United States and Canada), its former American subsidiary. Each has developed its own visual identity, and both have undergone significant logo redesigns in recent decades.
Design and History
Merck KGaA (Darmstadt, Germany)
For decades, Merck KGaA used a coat of arms featuring the “Chamomile Man” and the stylized signature of Emanuel Merck on its packaging, a system in place since the 1940s. In the late 1960s, the company decided to modernize. Director Hans Harms suggested designing a new logo to represent the company’s growth and high reputation, with the goal of demonstrating “progressiveness.” Kurt Weidemann, a professor at the Stuttgart State Academy of Art and Design, was hired as a consultant in 1967. Five agencies were invited to submit drafts. The jury selected a logo by Wim Crouwel of the Amsterdam agency Total Design, but the Patents department rejected it because the graphic element of six stripes was too unspecific and not protectable, as a UK company already had a similar symbol.[1]
The effort expanded into a comprehensive redesign of the company image. New design guidelines were introduced on February 28, 1969, and the “MERCK” lettering became the new, future-oriented logo. The management circular 2/1970, sent on March 5, 1970, declared the new company image official.[1]
In October 2015, Merck KGaA relaunched its brand identity with a fundamentally revised visual appearance and a new logo, reflecting its transformation into a global science and technology company. The rebranding project was executed by the brand agency FutureBrand.[2] The new logo was described as bolder and less complex than its predecessor, with the ability to be used in different colors.[2] The company also introduced a striking, multi-colored “M” design alongside the Merck logo, intended to create a visual link to its businesses in the US and Canada that operate under separate names (EMD Serono, EMD Performance Materials, EMD Millipore).[2]
Merck & Co., Inc. (US and Canada)
Merck & Co., Inc. has used a logo designed by Chermayeff & Geismar since 1965.[3] The design firm’s own project archive describes the work as a branding system created to unify the public presentation of Merck and its divisions, allowing for interaction between an abstract symbol and a custom-designed corporate wordmark.[4] The “MERCK” wordmark is used in the US and Canada, while the “MSD” wordmark is used outside these countries.[3]
Meaning and Symbolism
For the 2015 Merck KGaA identity, the official press release stated that the new design was inspired by the colorful and diverse shapes that can be observed under a microscope, giving the visual identity a scientific look and feel.[5] The new logo was described as more incisive and less complex than the previous one, reflecting the company’s evolution from a classic supplier of pharmaceuticals and chemicals into a global technology company.[2]
For the Merck & Co. symbol, the design consists of a bold mark made up of a capsule and two tablets alongside the “MERCK” logotype in capital letters. The symbol has been interpreted variously as a petri dish, mortar and pestle, or a medical cross.[6]
Typography and Design
Merck KGaA’s current logo is described by the company as “our name written using distinctive lettering.”[7] The company offers the logo in multiple color versions, including vibrant green and yellow.[7][8]
For Merck & Co., the Chermayeff & Geismar branding system included a custom-designed corporate wordmark, as documented by the design firm itself.[4]
