Herman Dirk van Dodeweerd (Amsterdam 1929-2018 Potsdam) was a Dutch sculptor, painter, writer, and violinist who adopted the name Armando as an artist and became an influential figure in the Dutch art scene. He studied at the Rijksakademie van Beeldende Kunsten in Amsterdam. His father was executed by the Nazis, and this had a profound impact on his artistic work. His sculptures often exhibit a robust and expressive style, while his paintings frequently display a certain roughness contributing to themes of violence and war. His work revolves around violence, perpetrators and victims, good, and especially evil. Even the landscape can be guilty, as it persists and overgrows places and memories. Evil resides in everything and everyone, and evil can be beautiful. Perpetrators become victims, and victims become perpetrators.

As a visual artist, he was part of the Dutch Informal Group founded in 1958 by Jan Henderikse  (also including Kees van Bohemen, Henk Peeters, and Jan Schoonhoven), which merged into the Dutch Nul movement in 1960.

In addition to his work as a visual artist, Armando was also a gifted writer, violinist, and TV program maker. He published essays, poetry, and prose, with "De Straat en het Struikgewas" considered his most accessible book. His writing often reflected on themes such as war, guilt, and memory. A recurring theme in his prose was the processing of the past by survivors of the war, especially the Germans themselves, and the various nuances he observed within it. As a poet and artist, he was also involved with De Nieuwe Stijl and Gard Sivik. He co-created the TV program "Herenleed" for VPRO with others, a surrealistic-absurdist sketch show in which he played the Underdog, alongside Cherry Duyns. As a violinist, he played with the Armando Quartet and the gypsy orchestra of Tata Mirando.

He played a role in establishing an artists' community in the former German military prison in Amersfoort. This complex became known as the "Armando Museum" from 1998, showcasing his work and that of other artists. From 1979, he lived alternately in Amstelveen and Berlin for over 25 years, working in the old studio of the Nazi sculptor Arno Breker until 1989. In 2007, a fire nearly destroyed the entire collection, and part of the rescued collection was transferred to the new Museum Oud Amelisweerd.

Armando had a lasting impact on the Dutch art world, both through his artistic contributions and his involvement in various artistic and societal issues. His work can also be found in Museum Het Valkhof, Joods Historisch Museum, Boijmans, Rijks, Stedelijk, and Voorlinden.
