Celebrating 150 years of Siegfried

Travel through time

Siegfried's early beginnings

In 1870, Samuel Benoni Siegfried, took over his grandfather’s pharmacy. Three years later, with his brother-in-law Johann Wilhelm Dürselen, he founded the company “Siegfried & Dürselen, Chemical-Pharmaceutical Preparations Production and Drugs Business.”

Benoni Siegfried soon recognized the market potential of producing pharmaceutical substances in larger quantities. In the early 1870s he declared “other pharmacists need the same basic substances as me. So, I’m going to produce ether, chloral and phenol in large volumes for them.”

Pharmacists realized that it was safer and easier to buy these substances rather than self-produce and in 1880, Benoni Siegfried stepped away from his pharmacy to fully focus on his industrial business. Right from the very start, Siegfried produced and packaged products for third parties – contract manufacturing – the core business today and a constant throughout the company’s 150-year history.

In the 1892/93 financial year, sales revenue passed the million-franc mark for the first time. By the turn of the century, Siegfried employed 60 people – five times more than when it started, and the best was yet to come!

Becoming a globally leading CDMO

Until the early 1980s, Siegfried offered a broad range of services. The family business developed and produced fine chemicals, specialist drugs and generics, pest control agents and natural products, trading them around the world. The company was branching out across the globe and had agents and licensees operating in more than 100 countries. From 1983 onward, Siegfried focused on the development and production of active pharmaceutical ingredients and drugs for the research-based pharmaceutical industry.

From 2010, the company grew to critical size thanks to acquisitions, crossing the one-billion mark in 2021. After shifting its focus to contract manufacturing, Siegfried’s global network also changed. The technology at the different locations is coordinated in such a way that individual production steps can be completed at whichever location can achieve the best possible quality at the lowest possible cost.

Today, Siegfried operates at 12 locations in seven countries on three continents. Eight of these have been acquired since 2012. In 2020, Siegfried took over two pharmaceutical production facilities from Novartis in Spain: Barberà del Vallès and El Masnou. In 2022, Siegfried broke ground on a new production facility in the German town of Minden. With a total investment of 100 million USD this was largest investment project in the company’s history.

The latest acquisition was DINAMIQS in May 2023 to build a best-in-class biotech CDMO for cell and gene therapies. Through this acquisition, Siegfried is expanding its footprint in the biologics space and will create significant growth opportunities in this exciting and dynamic market segment.
