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. Oil on canvas. Wooden frame. Size of frame: 14.75 x 13.5 inches.

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.
