The company traces its roots to the steam tractor machines manufactured by the Holt Manufacturing Company in 1890.[19] The steam tractors of the 1890s and early 1900s were extremely heavy, sometimes weighing 1,000 pounds (450 kg) per horsepower, and often sank into the earth of the San Joaquin Valley Delta farmland surrounding Stockton, California. Benjamin Holt attempted to fix the problem by increasing the size and width of the wheels up to 7.5 feet (2.3 m) tall and 6 feet (1.8 m) wide, producing a tractor 46 feet (14 m) wide, but this also made the tractors increasingly complex, expensive, and difficult to maintain.
Between 1907 and 1918, Best and Holt had spent about US$1.5 million in legal fees fighting each other in a number of contractual, trademark, and patent infringement lawsuits.[39] Harry H. Fair of the bond brokerage house of Pierce, Fair & Company of San Francisco had helped to finance C. L. Best's debt and Holt shareholders approached him about their company's financial difficulty. Fair recommended that the two companies should merge. In April and May 1925, the financially stronger C. L. Best merged with the market leader Holt Caterpillar to form the Caterpillar Tractor Co.[40]

Born in Hannah, North Dakota in 1902, Ginevra (Ginger) Irene Catherwood and her family moved to a homestead just outside Scott, Saskatchewan, four years later. Ginger likely learned to skate and play hockey on frozen sloughs. She also played baseball and excelled as pitcher. Catherwood entered the University of Saskatchewan on a scholarship in 1919. It was on the ice, as captain of the Varsity women’s hockey team, where she excelled. Catherwood’s arrival at the U of S coincided with the beginning of inter-varsity competition in women’s hockey. During the 1920-1921 season, playing against the University of Manitoba, Catherwood scored five goals in the first period and finished the game with three more in a 9-1 victory. She netted four goals in the first 11 minutes in a match against the University of Alberta. The final score was Saskatchewan 7 (Catherwood 6) and Alberta 1. The Saskatoon Star-Phoenix declared the U of S team the unofficial champion of university women’s hockey that season (there was no formal league at the time.) Opposing teams quickly learned that Catherwood was a scoring threat every time she had the puck. During the 1921-1922 season, she was hurt in the first period in a game in Edmonton and left the ice. The team squeaked out a 2-1 win. She was still nursing her injury in the next game against Manitoba and played defence in a 2-2 tie. Catherwood graduated with a three-year Arts degree in 1922. After attending Normal School in Saskatoon, she found work as a teacher in the Plenty, Saskatchewan district. Then in 1928, her sister Ethel won Olympic gold in high jump and Ginger was called upon by their family to chaperone her during her Canadian travels. Ginger was rumoured to have accompanied Ethel when she left Canada for the United States sometime around 1932. Ginger Catherwood later married English-born Charles Mitchell in Toronto in the fall of 1933.

The Catholic Women's League was originally organized in England. Units of the League were established in Edmonton in 1912, Montreal in 1917, Toronto and Ottawa in 1918, and Halifax, Regina, and Sherbrooke in 1919. The dream of a Dominion-wide organization began to take shape during the week of June 19, 1920 when existing units of the League and several other groups of Catholic women came together to "unite Catholic women in an organized body in order to secure the influence needed for promotion of Catholic Social Action, Catholic Education, and Racial harmony with the Catholic Church in Canada." Their motto was "For God and Canada."

The Canadian League became affiliated with the International Union of Catholic Women's Leagues, later called the World Union of Catholic Women's Organizations (WUCWO). Catholic women across the country were encouraged to join the new organization. The first subdivision of the League in Saskatchewan was organized at Holy Rosary parish in Regina on September 8, 1919. The League was established in other communities such as Saskatoon, Prince Albert, Muenster, and Gravelbourg.

In 1943 the National Executive resolved to set up provincial committees of the Catholic Women's League in order that the League be in a position to seek representation for Catholic women on the official provincial committees set up by provincial governments of to deal with war, postwar and other patriotic projects. Ellen M. Drake, President of the Diocesan Council of the Archdiocese of Regina in 1943, was subsequently appointed Chair of the Provincial Council Committee. She was elected the first president of the Saskatchewan Council at the organizational meeting held in Rosary Hall in Saskatoon on March 12, 1948.
