Danish stage and film star, regarded for more than 50 years as one of the most important character actors in Denmark.

After studying at the Royal Theatre, Reumert began his professional career at the Copenhagen Folk Theater in 1902. In 1911 he moved to the Royal Theater, where he spent most of his career and developed a lifelong stage partnership with the actress Bodil Ipsen (Ipsen, Bodil).

A consummate character actor, Reumert was known for his subtle style and clear delineation of personality, talents that proved equally adaptable to the diverse works of Ludvig Holberg, George Bernard Shaw, Henrik Ibsen, and others. His most celebrated parts, however, were Molière's Tartuffe and several roles in the plays of William Shakespeare and the modern Swedish dramatist August Strindberg. He appeared several times with the Comédie-Française, where he delighted audiences with his perfect French. He also made a number of films in the 1930s and '40s.
