Nicolay (or Nicola) Diulgheroff (Kustendil, 20 December 1901 - Turin, 9 June 1982) was a Bulgarian painter, designer and architect linked above all to Futurism.
After a brief spell in Vienna and Dresden, he studied initially in Weimar at the Bauhaus. After meeting some exponents of the Second Futurism including Fillia, in 1926 he moved permanently to Turin. Here he joined the futurist group, with which he began to exhibit his first works, also dedicating himself to painting and industrial design. He then collaborates with several futurist magazines including "La Città Nuova" and "Futurist style".
In 1928 he participated in the XVI Venice Biennale, in the room dedicated to the futurists. He works as a poster designer at an important advertising company creating a series of advertising boards on sheet metal.
In 1930 he was present again at the Venice Biennale, then at the "Futurist Exhibition" in Alessandria and at the "Mostra Amici dell'Arte" in Turin. He also creates interiors for apartments and shops, furnishing the "Futurist Taverna del Santopalato" with Fillia.
In 1932 he graduated in architecture from the Royal Albertina Academy, and two years later he finished the construction of a private house in Albisola Marina, which he designed in a rationalist style.
However, architecture remained a fairly secondary activity. Diulgheroff favored mainly advertising graphics (his was the red spiral of the bitter Cora), the layout of pavilions and the furnishings of shops and homes; he also continued to devote himself to painting in the futurist style, working hard on the intersection of lines, planes and spheres.
In 1976, on the occasion of the centenary of Marinetti's birth, he created a series of litho-seri-collages entitled Marinetti Rotante in Divenire
