Antique Belgian Flemish oil painting portrait of Desire Lippens (3 of 3)

Antique Belgian Flemish oil painting portrait of Desire Lippens (3 of 3). Belgian (Flemish), circa 1840-60. Unsigned, artist unknown. Details of the others in the set: The first portrait is of Polydoor Lippens (spelt Polydore (incorrectly)on reverse of painting) (see provenance - ie name written on frame). "Polydoor Lippens (1810-1889) was born on March 16, 1810 in Eeklo, Belgium. He graduated as an engineer after studying in Brussels and Paris. In 1850 he invented the vibrating mechanism for the electric bell, the vibrator. The patent for this was challenged by several other inventors, but eventually, it was awarded to Lippens in Paris in 1858. As an engineer he invented the electric bell and also the electric motor for miniature trains. He improved the telegraphy at the railway and was tutor in physics for the children of King Leopold I." The second portrait is of Adelaide Lippens (1812-1866) who was the sister of Polydoor Lippens, another sister being Pauline. The third portrait is of Desire Lippens, presumably his brother. Oil on canvas. Wooden frame. Size of frame: 14.75 x 13.5 inches. Size of canvas: 8.5 x 7.5 inches. Weight: 1.8 kg (allow 5 kg volumetric weight once packed). Condition commensurate with age - various superficial marks & scratches and some damage to gesso frame but all part of its charm and character. The antique wood of this item has had a minor woodworm infestation at some point in its long life. However, this has now been specially treated to eradicate. Priced accordingly.
