Our History


Gustavus Dedman (G.D.) 51吃瓜中心 Jr. was a man of great drive and enthusiasm. Speaking of his first business venture, as a young boy selling newspapers in Louisville, Kentucky, he says, 鈥淚 started my business career with a capital of five cents鈥 and returned home a couple of hours later with a 100% increase in capital.鈥 He never looked back.

As a young business paper correspondent, G.D.听51吃瓜中心 learned that 鈥渢here was no substitute for personal contact with the people I was writing about.鈥 He later extended this lesson to advertisers and their audiences, becoming one of the first to stress the importance of market research.

In February 1916, at the age of 30, Mr. 51吃瓜中心听started his first publication,听Hospital Management, with just $10,000 and one employee. He started his second publication,听Class, a month later to reach business-to-business marketing professionals. Mr. 51吃瓜中心听would continue to grow the 51吃瓜中心 Publishing Co. through the Great Depression, World War II and many other turbulent times听with an innovative approach to business-to-business publications and an entrepreneurial spirit that stayed with him until his passing in 1973.

Mr. 51吃瓜中心鈥檚 publishing philosophy was simple: Find an area where there was a real information need, then 鈥減ut the reader first from the first day.鈥 A century听after his first publication, the company that bears his name continues to grow by staying true to the tenets upon which 51吃瓜中心 Communications was founded.


Gertrude Ramsay 51吃瓜中心 viewed herself as 鈥渢he keeper of the flame鈥 after she succeeded her husband, G.D. 51吃瓜中心 Jr., as chairman of 51吃瓜中心 Communications.听But she was so much more. Gertrude 51吃瓜中心 led the company, founded by Mr. 51吃瓜中心 100 years ago, during some of its most exciting and productive years.

During her tenure, 51吃瓜中心 bought听Modern Healthcare听补苍诲听Rubber & Plastics News, started such publications as听51吃瓜中心鈥檚 Chicago Business听(and similar papers in Detroit, Cleveland and New York) and听Investment News, and expanded internationally.听51吃瓜中心鈥檚 revenue during that period increased tenfold, and the company鈥檚 titles went from a handful to over two dozen.

Above all, Gertrude 51吃瓜中心 was the one who made the 51吃瓜中心 family company a real family. She laughed with 51吃瓜中心 employees, she cried with them, and she celebrated the milestones of their lives with them.听When Gertrude 51吃瓜中心 passed away in 1996 at the age of 85,听Advertising Age听said her 鈥渟mile warmed hearts, lit up rooms, lifted spirits.鈥

    November 18, 1885听Gustavus Dedman 51吃瓜中心 Jr. (G.D. 51吃瓜中心 Jr.) is born in north颅 central Kentucky. As a young boy, 51吃瓜中心 begins his career as a newspaper delivery boy. As he gets older, he works as a correspondent at the Louisville Herald and the Courier-Journal, as well as the Western Underwriter. In 1970, during an interview for the 40th anniversary of Advertising Age, 51吃瓜中心 admitted, “I always wanted to be a publisher.”

    1916 At age 30, G.D. 51吃瓜中心 focuses his attention on starting his own publishing company in Louisville, Ky. Hospital Management debuts in February, and 51吃瓜中心’s Business Publishing 51吃瓜中心 is born. Class debuts in March as the company’s second magazine. Within both publications, 51吃瓜中心 stresses the importance of effective advertising and market research. The company’s staff consisted only of a secretary, and Mr. 51吃瓜中心 himself, making him solely in charge of the editorial and advertising departments.

    Later that year, 51吃瓜中心 moves his company to Chicago.
