fulfill a short-term commission from the War Artists Advisory Committee. It falls precisely within Lowry’s principal oeuvre. The artist fills the foreground with countless anonymous factory workers trudging through the snow, dutifully coalescing into distinct queues as they march toward the bulwark of grim buildings to begin manufacturing machinery and motors at the iconic Mather & Platt foundry, Manchester (which continued operating in some capacity under various owners until July 2017). Crowded between and before the buildings, numerous less-distinct figures swell the ranks of workers toiling to support the war effort. Viewers, as are Lowry’s workers, are inevitably drawn toward the row of buildings dominating the center of the painting. A single smudge of green partly obscured by the double-decker bus suggests a lone tree. Wires stretch across the top of the canvas, and hovering ominously overhead, a pair of barrage balloons offers modest defense from aerial attacks on the factory compound. Lowry did not consider art a medium for agitation or activism. In his words, “To say the truth, I was not thinking very much about the people. I did not care for them the way a reformer does. They were part of a private beauty that haunted me. I loved them and the houses in the same way, as part of a vision. Had I drawn them as they are, it would not have looked like a vision.” When Lowry died of pneumonia on February 23, 1976, he was both wealthy and well known as an artist and art collector. A few months after his death, the Royal Academy’s retrospective exhibition of his works achieved the record number of visitors for any exhibition by a British artist up to that time. About 5 months after Lowry’s death, an outbreak of a new type of pneumonia, now known as Legionnaires’ disease, occurred among attendees at an American Legion convention in Philadelphia, Pennsylvania, USA. Legionella bacteria can cause Legionnaires’ disease or Pontiac fever, collectively known as legionellosis. Legionella bacteria are found naturally in freshwater environments but can infect humans when they grow and spread in manufactured water systems. Viruses, bacteria, and fungi can all cause pneumonia. Many of those factory workers who inspired Lowry’s nameless matchstick men may have also died of the disease that ultimately took Lowry. In the 3rd edition of his classic textbook The Principles and Practice of Medicine (1898), Sir William Osler describes pneumonia as “the old man’s friend,” because death from pneumonia seemed to involve less obvious agony than other common causes of death. Despite the availability of vaccines and antibiotics and the remarkable advances in respiratory care, pneumonia continues to affect hundreds of millions of people, old and young, in all parts of the world and also remains the single largest cause of child deaths worldwide.
