Harrison King McCann (November 4, 1880 – December 20, 1962), was the founder of the H. K. McCann Company. H. K. McCann Company was an advertising agency that, as McCann Erickson, grew to become the world's largest with a global network of offices in more than 130 countries, providing advertising campaigns for brands including Standard Oil (Esso, Exxon), Vaseline, Beech-Nut, Del Monte, Nabisco, Coca-Cola, General Motors, Martini, Gillette, L’Oréal, Bacardi, Nestlé, R.J. Reynolds and MasterCard.
McCann was born in Maine on November 4, 1880 to a New England family that had settled in New Hampshire in the seventeenth century. In 1902 he graduated from Bowdoin College in Brunswick, Maine, where he had worked on the student newspaper and been leader of the mandolin club.
During his high school and college years he worked for Hiram Ricker & Sons, hotel proprietors in Poland Spring, initially as a bellboy and later as salesman for Poland Spring water. This job took him to the Poland Springs New York office.
Once in New York, McCann switched jobs, joining the Amsterdam Advertising Agency as copywriter in 1903. In the same year he was offered a position by the New York Telephone Company, and put in charge of an experimental campaign to discover if advertising could prevent the company from losing customers to smaller competitors. By 1910, McCann was successfully running an in-house department of 100 staff.
McCann's work for the New York Telephone Company attracted the attention of the Standard Oil Company, who recruited him to lead their in-house advertising department. When the US Government ordered the break-up of the Standard Oil Company on monopoly grounds, McCann formed his own agency with Canadian efficiency expert Herbert Newton Casson to provide ad continuity.
The H. K. McCann Company opened its doors on Broadway, New York in 1912, with Standard Oil as its first account. By its second year it was handling over $200,000 worth of business. A network of offices across North America quickly followed. In 1928, McCann opened its first European offices in Berlin, London and Paris. In 1930, McCann merged with Alfred Erickson's agency to form McCann-Erickson.
McCann and the number thirteen
While triskaidekaphobia – fear of the number 13 – is a common, if usually mild phobia in the US, McCann felt that it was his lucky number.
He had begun his job with the New York Telephone Company on October 13, 1910, he made the decision to form his own agency on November 13, 1911, and he went on to weave the number into the lore of the agency. He often shortened the company name to The H K McCann Co to have the right number of letters. The agency's famous and still used credo "Truth Well Told" also contains 13 letters, and whenever his growing agency moved to new buildings, McCann would insist on a thirteenth floor office.
When McCann-Erickson moved to the newly built 50 Rockefeller Plaza in 1939 he demanded a 13th floor, and placed his office on it. It remains the only building in the Rockefeller Center to have one.
