The company was founded in 1907 by Otis Kline and Richard Massey. Headquartered in Sterling, Illinois, it was then called Massey's and was focused on the production of fragrances for cleaning products. In 1917, the company moved to Webster Avenue in Chicago to be closer to a transportation hub., and Chatfield Nielsen Sr. joined the company's leadership. Nielsen and Massey worked together to focus the company on manufacturing a variety of vanillas and other flavors, primarily for sale to food manufacturers. In 1954, upon the passing of Richard Massey, Nielsen purchased the company from the Massey family. His son Chatfield Jr. joined the company in 1958 and ultimately become vice president in 1963. This same year, the company was renamed Nielsen-Massey. Chat later succeeded his father as president and focused on making Nielsen-Massey “pure vanilla specialists”— producing only all-natural vanilla products. In 1979, Chat's wife Camilla joined the company's leadership team. Until the early 1980s, Nielsen-Massey only sold its products to industrial and foodservice customers. But in 1980, they were contacted by a then-unknown Chuck Williams, who wanted to place an order for 20,000 bottles of vanilla extract to sell at his retail store – then just a hardware store in Sonoma, California that also sold French cookware. That initial order led Nielsen-Massey to create a retail product line, bottling 8 oz. packages exclusively for Williams Sonoma, and Nielsen-Massey has continued to be sold in its stores, catalogs, and website ever since. In 1984 the company moved out of downtown Chicago, relocating its production to suburban Lake Forest, Illinois, and then later moving to Waukegan in 1992 in order to increase plant size and expand production. After Chat's passing in 1992, Camilla took over company leadership. The third generation of the Nielsen family started joining the company in 1986, with the addition of Chat and Camilla's oldest son Craig, followed by younger son Matt in 1994. In 2006, their daughter Beth also joined the company. The company expanded in the 1990s, first with the plant move to Waukegan, then with the opening of Nielsen-Massey Vanillas International, LLC in Leeuwarden, Netherlands in 1995. They also developed new vanilla products beyond just traditional extract, starting with Madagascar Bourbon Pure Vanilla Powder in 1995, then with Madagascar Bourbon Pure Vanilla Bean Paste in 1998. In 2005 the company introduced a line of flavor extracts, including almond, chocolate, coffee, orange, and peppermint. Also in 2005, Camilla Nielsen retired from Nielsen-Massey, and her children Craig, Matt, and later Beth took on leadership of the company. In 2017 the company established an outside board of directors and Kirk Trofholz became CEO. In 2018, it announced No Sugar Added Vanilla Extract and an organic line of flavor extracts
