Information on von Ueberfeld is difficult to find. The only reference I can find on the web accompanies this illustration:

Wie mij kan helpen aan informatie over Jan Braet von Ueberfeld kan rekenen op mijn dankbaarheid. Op de expositie hangt een blad uit het boek dat hij samen met Valentijn Bing maakte: "Nederlandsche kleederdragten, naar de natuur geteekend." (1807 geboren in Langerak, 1894 gestorven in Doetinchem). De man wordt in elke studie over Piet Mondriaan vermeld als een van de leermeesters van de jonge Piet toen die in Winterswijk woonde. Ook bevat de collectie geen enkel werk van kunstenaars die recent actief zijn geweest in Doetinchem. Ik mis bijvoorbeeld werk van Jos Klaver of Theo van Koot.

This might translate (courtesy of Babel) as,

They who me can help to information on Jan Braet von Ueberfeld can count on my gratitude. On the expositie a booklet hangs from the book which he made with valentijn Bing: "Nederlandsche kleederdragten, to nature geteekend." (1807 born died in Langerak, 1894 in Doetinchem). The man is mentioned in each study concerning piet Mondriaan as of the learning masters of the young piet then who lived in winter district. Also the collectie absolutely no work of artists contains which has been recent active in Doetinchem. I miss for example work of Jos clover or Theo van Koot.

George Hendrik Breitner was born in Rotterdam in 1857. In 1876 he enrolled at the academy in The Hague, Breitner passed the drawing exams within a year. However, he was not enthusiastic about the academy's rather traditional educational principles and within a few years he was expelled for 'unruly conduct'.  Later, he worked for a number of years in Willem Maris' studio and helped produce the Mesdag Panorama in Scheveningen. In this early period he was especially influenced by the painters of the Hague School. After moving to Amsterdam, he decided to complete the course at the Amsterdam Rijksacademie. But by now Breitner was a famous artist with his own individual style and his return to college was less than successful.
In 1882 he met Vincent van Gogh, with whom he often went sketching in the poorer areas of The Hague. Breitner preferred working-class models: labourers, servant girls and people from the lower class districts. He saw himself as 'le peintre du peuple', the people's painter. Interest in the lot of the common people, which many artists felt in that period, was nurtured by the social conscience of French writers such as Emile Zola.
Breitner gradually drifted away from the Hague School. In 1886 he moved to Amsterdam, where he recorded the life of the city in sketches, paintings and photos. Sometimes he made various pictures of the same subject, from different perspectives or in different weather conditions. Photos sometimes formed the immediate example for a particular painting, for instance the girls in kimono. On other occasions, Breitner used photography for general reference, to capture an atmosphere, a light effect or the weather in the city at a particular moment.
Breitner painted with a loose brushstroke in an impressionist style. He often worked with Isaac Israels; both painters are counted among the Amsterdam Impressionists. Critics often referred to Breitner's manner of painting as 'unfinished'. But among the younger generation of writers and critics his innovative manner of painting and his Bohemian lifestyle were greatly admired.

Dutch painter, born in Java. Studied art in Delft and Amsterdam. A grant allowed him to study in Brussels, where he came into contact with the XX group, and became a member in 1885. He befriended Khnopff, Ensor and de Groux. In 1886, he met Whistler in London. He discovered the Pre-Raphaelites and William Morris' views on art and socialism. In 1890 he developed his own version of Symbolism using elements of a Javanese aesthetic. Met Péladan in 1892. In 1905 converted to Catholicism. His themes thereafter became religious and even mystic. His style simplified and he adopted a technique close to Pointillisme, which he put at the service of a fragmentation of the surface of the painting at poles from the measured unity to which Seurat aspired. These fragmentary surfaces relate Toorop to Expressionism.

After a first period fauvist, it was directed towards the cubism before turning to a expressionnism inspired of Van Gogh. It painted scenes of the everyday life, portraits and the naked ones.
