The story

In 1923 Hugo Knümann founded a commercial agency for electrical products and sells contact wire terminals for electric trams in Essen, Germany. Two floors of a rented building in Essen served as the company headquarters: offices were on the first floor; the second story was used for assembly. Soon after, the young company became "Phönix Elektrizitätsgesellschaft" (Phoenix Electricity Company).

Working together with Rhine-Westphalia Electricity Works (RWE), Hugo Knümann developed the first modular terminal block in 1928.

In 1937 Ursula Lampmann, later to become one of the partners, joined the company as the first commercial member of staff. For almost six decades, she had an active role in the company.

On March 13, 1943 the company offices near the Essen train station were destroyed in a British air raid at the Battle of the Ruhr in World War II. The company headquarters moved to the "Bürgerheim" restaurant in Blomberg. 1948 that part of the 30-strong company moved back to Essen.

Hugo Knümann enlisted Josef Eisert, who owned numerous terminal block patents, as technical director for his company in 1949. Eisert revised the entire product range. Following the death of Hugo Knümann in 1953, Josef Eisert and Ursula Lampmann took over the management of Phönix Klemmen. Through a merger, sister company Phoenix Feinbau was created in Lüdenscheid – this marked the birth of the future Phoenix Contact Group.

In 1957 Phoenix opened the first two production facilities at the Flachsmarkt site in Blomberg. Phönix Klemmen employed its first apprentice, Helmut Conrad. In 1961 Klaus Eisert, son of Josef Eisert, joined the company as a managing partner. He remained in this role as of 2018. His brothers Jörg and Gerd join the company in the following year. In Phoenix closed the facility in Essen. At this time more than 300 employees now work at the company's headquarters in Blomberg.

Up from 1981 Phönix Klemmen started establishing subsidiaries in foreign markets. The subsidiary in Switzerland marked the first in 1981. Sweden and the USA followed in the mid-1980s. As of 2018, Phoenix Contact is represented in over 50 countries.

Phönix Klemmen changed its name to the more international Phoenix Contact.
