People were used to carrying candles around the home, so cabin lamps were designed to be similar. When they weren’t attached to a hook on the wall, they could be carried around the cabin and placed on desks.
This gimbal lamp is a rare survivor and still retains its electrical cord, switch and bulb holder. Manufactured by William McGeoch, lamps such as this adorned both first and second class cabins onboard the RMS Titanic and Olympic.
