In North America, the device known as a hemometer is usually referred to as a haemocytometer. This tool was originally invented by Louis-Charles Malassez, a 19th-century French anatomist and histologist. The item shown was manufactured in the American city of Philadelphia in 1940 by Arthur Thomas & Company, according to a design patented by Dr Max Levy in 1917.

The United States was a significant exporter of medical instruments to Australia during the twentieth century. Haemocytometers were originally introduced to the United States by doctors from Europe in the 19th century. The item is in mint condition, suggesting that it was infrequently used.
