Dr Patrick Lane, from Quinpool, Parteen, joined the British army after graduating from the National University.
Serving in the Royal Army Medical Corps, he led the stretcher-bearers and had to provide medical treatment for injured soldiers in the middle of the battlefields under heavy fire before they were brought to safety.
According to a historical account, on one occasion, Dr Lane was speaking to another doctor when a shell fell between them, killing his medical colleague.
As a result of his service and bravery, he was awarded the Military Cross, one of the highest decorations that the British state can award. Later in the war, he was awarded an additional bar .
Having returned to the mid-west, he worked with Limerick County Council as a doctor, tuberculosis officer, and school examiner. He died in 1968 at the age of 72 .
Details about his life have emerged thanks to the efforts of his grandnephew, Tommy Lane, and his niece, Mary Hourigan O’Brien, who brought copies of documents and photographs into Limerick Museum.
Limerick Museum said the exhibition, Stand Up and Fight: Limerick’s Military History from the Wild Geese to Gallipoli, which will be launched on Thursday and runs until the end of the year, also features items from Limerick Museum’s own collection as well as donations from the public.
