Rue des Fontenelles has dated this Antique Female Oil Portrait to the 19th Century.
Keller was a German painter of Swiss ancestry. He specialized in portraits and indoor scenes. Female figures are a prominent feature of his work.
He made numerous study trips throughout Germany, France, Italy and the Low Countries. From 1867, he worked at several different studios throughout Munich, including that of Arthur von Ramberg, where he drew nude studies. He had his first showing at the Glaspalast in 1869 and became a member of Allotria - an artists' association, in 1873.

In 1878, he married Irene von Eichthal (1858–1907), great-granddaughter of the Bavarian Court Banker, Aron Elias Seligmann, Freiherr von Eichthal. He would eventually paint over forty portraits of her. Their first son died as an infant. Their second son, Balthasar, was born in 1884, but died in 1906, shortly before his mother.

He exhibited at the Salon for the first time in 1883, while living in Paris. In 1886, he became a member of the new "Munich Psychological Society"; actually a group devoted to the paranormal, founded by Albert von Schrenck-Notzing. Soon he began representing parapsychological motifs, connected to Christian themes, with visions and hallucinations. In 1892, he was one of the co-founders of the Munich Secession and served as vice president from 1904 to 1920. He was also a board member of the Deutscher Künstlerbund. In 1898, he received the Knight's Cross of the Order of Merit of the Bavarian Crown, which entitled him to use the noble "von" in his name.
