SUSAN DAVIS – INVENTOR – Article written by Jessica Young for Canadian Encyclpedia.
Early Life and Education
Susan Olivia Davis was born to Miles Franklin Davis and Charlotte Warren in Devils Lake, North Dakota. She spent her childhood on White Earth Reservation in Minnesota.
Olivia was a talented pianist and went on to study music at Brandon College in Manitoba. While in Manitoba, she met Delbert Poole and the two were married in 1909. They had seven children together, first moving to Ontario before settling in Vancouver in 1942.
Invention of the Jolly Jumper
On White Earth Reservation, Olivia Poole saw mothers using cradle boards as baby carriers. Cradleboards allowed mothers and caregivers greater freedom to work or perform their daily routine while their baby was safely secured on the board. Some mothers suspended cradleboards from a sturdy tree branch or structure to act as a hammock or swing, providing the baby with amusement. Poole witnessed mothers pulling on the ropes or leather straps suspending the cradleboard to bounce the baby up and down. This allowed mothers to work uninterrupted while the babies entertained themselves with the bouncing motion.

In 1910, after Poole had her first baby, she remembered how mothers on White Earth Reservation used this cradleboard technique to calm their babies. By this time, she was living in Ontario and did not have a cradleboard of her own. Instead, she fashioned one with items from around her house. She sewed a cloth diaper into a harness and created a brace with an axe handle. This device was different than a cradleboard, as the baby’s legs dangled freely and there was no rectangular board attached. Eventually, she added a spring and rubber connection so that the baby could bounce on its own. Her swing was low enough for the baby’s toes to reach the ground, allowing the baby to exercise its leg muscles.
Poole called her invention the “Jolly Jumper” and she used it for all seven of her children. When her children were grown, she continued to make improvements to the baby jumper design for her grandchildren. Given its success within the family, Poole’s family convinced her to market her invention. By the early 1950s, Poole’s Jolly Jumper went into mass production for retail. Her eldest son, Joseph, helped her file and apply for a patent in 1957 where her invention is called the “Baby Supporter and Exerciser.” Together, they created Poole Manufacturing Co. Ltd. which was based in British Columbia. The Poole family sold the business in the 1960s but today the Jolly Jumper brand is owned by a company based in Mississauga, Ontario.
