The descendants of Roscoe C. Merchant, founder of the R.C. Merchant & Co. manufacturing rep firm in Farmington Hills, are impressed their forefather took a chance and joined the nascent electronics industry in 1924.
“We started as an electronics component rep,” says Brook Merchant, chairman of R.C. Merchant and grandson of the founder. “The only product was the radio. We first started selling tube sockets. After that, we went to tube testers and evolved until the invention of the transistor in the 1950s.”
Until the late 1930s, the Merchant firm was a one-man operation, with Roscoe working out of an office in the Hayward building in downtown Detroit. There, he met Ethel Marquardt, who worked in an adjacent office. Soon, she undertook part-time secretarial work for Roscoe. In 1942, Marquardt joined the Merchant firm full time.
The original Merchant enterprise had one client, a company called Jewell Electrical Instrument Co. in Chicago. Today, the company represents as many as 15 electrical and electronics component manufacturers including Eaton, Mitsubishi Electric, and Grayhill.
In 2026, 70 percent of the company’s business is automotive, mostly comprised of capacitors and passive electronic components that store electrical energy in an electric field by accumulating a charge on two closely spaced, insulated conductive plates.
“We sell these little things called capacitors,” Merchant says. “A car used to have 2,000 of them. Now they have 30,000. Even if they make fewer cars, our content continues to increase. That’s how we’ve grown so much over the last 10 to 15 years.”
Between Roscoe Merchant and Brook Merchant, and new president Mallerie Merchant — daughter of Brook and great-granddaughter of Roscoe — was John Merchant, who was convinced to drop out of college to take over for Roscoe when he was stricken with cancer in 1959.
“He had to sink or swim, and he survived pretty well,” Brook says of his father’s time at the company’s helm.
R.C. Merchant & Co. has grown from a humble beginning to an enterprise with regional operations across the Great Lakes — including Michigan, Indiana, Ohio, and Kentucky. The company maintains two divisions: the largest representing electronic components and the other representing electrical manufacturers, which focuses on data centers.
“There’s new technology emerging that’s really good for the rep model,” Mallerie Merchant says. “There’s a huge need for manufacturers who want to take their technology to market, and they don’t have the capabilities in customer relationships or the money to hire a sales staff.”
More than salespeople, Merchant’s reps function much like technical advisers, according to the company.
Although technology is bringing change to every industry, Mallerie Merchant sees a bright future for the company that she’s leading into its second century.
“We’re seeing a shift in how typical rep agreements are structured, due to industries becoming more global,” she says. “But I don’t think we’re seeing a decrease in the need for a technical salesperson who has deep relationships. Technology can replace some of the administrative things associated with sales, but it doesn’t replace the relationships.”
Relationships, expertise, and experience are what have kept R.C. Merchant going for more than 100 years.
“We have a lot of tenure on our sales team,” Mallerie Merchant says. “The most important thing for a rep firm is relationships with your lines (products) and your customers. There are customers with whom we have multigenerational relationships.”
Brook Merchant says the success and longevity of the company that bears his name is due to more than technical expertise.
“We strive to forge really close relationships with our customers,” he says. “That developed because of our integrity and our morals. We don’t lie. We don’t cheat. We don’t hold people up for kickbacks, which is stuff that used to go on in Detroit.”
