The most famous Latvian organ builder over the end of the century was Martins Kreslins (Martin Kresling, d. 1911) from Jekabpils, who built about 130-140 organs and harmoniums. Some of his instruments still exist today; for example, in Bauska (1891, III/P/36), in Araisi (1904, II/P/15), in the church of Usma (1879, II/6) (the church was transferred to the holdings of the Ethnographical Museum in 1936).
