"Johann Michael Wittmer (15 October 1802, Murnau am Staffelsee - 9 May 1880, Munich) was a German painter who came from a family of painters and sculptors and was associated with the "Deutschrömer" (Germans artists and writers who lived in Rome). He is often referred to as "Johann Michael Wittmer II", to distinguish him from an earlier family member of the same name." - (en.wikipedia.org 30.01.2020)
