Born in 1891 in Ulcinj, Montenegro, Marco Dobretsovitch trained in Augusto Pollastri's workshop in Bologna during the first half of the 1920s. He later relocated in Cairo, Egypt, and continued his career as a luthier there, then moving to Alexandria and returning to Cairo again after the war. The date of his death is not known with certainty, but it must be after 1960.
His style has some similarities with Pollastri, in particular in the treatment of the edge and in the shape of the F-holes, although Dobretsovitch also used models inspired by Guarneri del Gesù and Guadagnini. The corners, especially during his last period, are wider and squarish and the scroll is quite geometrical and not as soft and spontaneous as in the Pollastri brothers, but the quality of his work and his style are comparable to the best instruments of the Bologna tradition.
