Heinemann and Mondschein (Frederick Mont) in provenances of artworks in American museums

Aug 27, 2020
SEVEN DATASETS: Frederick Mont or Galerie Sanct Lucas in the Provenance of Artworks
Frederick Mont (1894-1994) was an art dealer who sold artworks to dozens of major art museums and art collectors.
Mont, originally named Fritz Mondschein, owned the Sanct Lucas Gallery.
Mont is known to have worked with the Austrian Nazi SS art dealer and looter Bernhard Witke and was involved in selling at least two artworks looted from the Jewish collector Julius Priester, including the El Greco, Portrait of a Gentleman.
Mont also sold a forgery to Sherman Lee at the Cleveland Museum of Art as a Grunewald, but, according to the NYT, pigment tests conducted by the museum's conservator, Ross Merrill, proved conclusively that the painting was a 20th‐century forgery.
The provenances of those artworks were falsified, with fake owners and entirely fake histories inserted into the texts.
Art historians, provenance researchers and scholars of the Holocaust should keep this context in mind when evaluating the ownership histories that have been published for artworks that passed through Mont's hands.
Mont was not an honest man. Everything Frederick Mont or his Galerie Sanct Lucas claimed about an artwork should be considered questionable unless it is proven to be true.

Nazi looted art: deception by provenance authors
The web of complicity is tough to break through, and it is rather depressing to even try.
However, inspired by recent events, we will in this next series of posts, attempt to highlight of few of the tricks used by various art market actors to disguise what they clearly suspect to be illicit origins.
In this first post, we revisit the El Greco, Portrait of a Gentleman, that was part of the Julius Priester collection before the Holocaust.

Art Dealers in Provenance: Frederick Mont at the Toledo Museum of Art and LACMA
Art dealers like Frederick Mont played an important role in bringing art to American museums.
In previous posts we looked at the biography of Frederick Mont, also known as Frederick Mondschein (1894-1994), and mentions of his name in the provenances of artworks that are now at the National Gallery of Art in Washington DC.
In this post, we look at the provenances of some of the artworks that Mont dealt with that are now in the art collections of the Toledo Museum of Art in Ohio and LACMA in Los Angeles.
Several of these provenances exhibit gaps in the years 1933-1945.
