The story

Founded by J.B. Wolters Publishing in 1987.1

Early history

Jan-Berend Wolters founded the Schoolbook publishing house in Groningen, Netherlands, in 1836. In 1858, the Noordhoff publishing house was founded alongside the Schoolbook publishing house. The two publishing houses merged in 1968. Wolters-Noordhoff merged with Information and Communications Union (ICU) in 1972 and took the name ICU. ICU acquired Croner in 1977, ICU changed its name to Wolters-Samsom in 1983. The company began serving foreign law firms and multinational companies in China in 1985. In 1987, Elsevier, the largest publishing house in the Netherlands, announced its intentions to buy up Kluwer's stock. Kluwer merged with Wolters-Samsom to fend off Elsevier's takeover bid and formed Wolters Kluwer. The merger made Wolters Kluwer the second-largest publishing house in the Netherlands.

After the merger, Wolters Kluwer began expanding internationally with the purchase of IPSOA Editore, Kieser Verlag, Technipublicaciones, and Tele Consulte in 1989. By the end of the year, Wolters Kluwer expanded its presence to Spain, West Germany and France. The company also launched LEX, its legal information system, in Poland. In 1989, 44% of the company's revenue was earned in foreign markets.

1990s

The following year, Wolters Kluwer purchased J. B. Lippincott & Co. from HarperCollins. The company acquired Liber, a Swedish educational publishing company, in 1993. The following year, it established its first Eastern European subsidiary, IURA Edition, in Bratislava, Slovakia. The company acquired Jugend & Volk, Dalian, Fateco Fîrlag and Juristfîrlaget, Deutscher Kommunal-Verlag Dr. Naujoks & Behrendt, and Colex Data in 1995. Wolters Kluwer was operating in 16 countries and had approximately 8000 employees by the end of that year.

In 1994, Wolters Kluwer expanded its US legal business by acquiring Prentice Hall Law & Business from Simon & Schuster. In 1995, Wolters Kluwer acquired CT Corporation. The following year, it purchased CCH Inc., a tax and business materials publisher, for $1.9 billion. The purchase assisted in expanding the company's business in Asia because of CCH Inc.'s involvement in Australia, New Zealand, Japan, Singapore, and Hong Kong. It also purchased Little, Brown and Company's medical and legal division that year. John Wiley & Son's legal division was purchased in 1997. Waverly, Inc., Ovid Technologies, Inc. and Plenum Publishing Corporation were acquired in 1998 to develop Wolters Kluwer's medical and scientific publishing industry.

2000s

In 2002, Wolters Kluwer sold Kluwer Academic Publishers to the private equity firms Cinven and Candover Investments. (It is now part of Springer). The company established its first three-year strategy to deliver sustained value to customers and shareholders in 2003. The New Delhi Wolters Kluwer Health office opened in 2006. In 2007, Wolters Kluwer Education was sold to Bridgepoint Capital. In September 2008, Wolters Kluwer acquired UpToDate, an evidence-based electronic clinical information resource. The following month, the company received a multi-year contract to provide prescription and patient-level data to the United States Food and Drug Administration. In 2009, Wolters Kluwer was named the "Best Place to Work" in Spain by the Great Place to Work Institute.

2010s–2020s

Wolters Kluwer Deutschland, the German subsidiary of the company, launched Legal Tribune Online in April 2010. The online magazine, which provides German-language news and analysis about current developments in law and related subjects, ranked among the top 20 most visited online professional journals. In September of that year, Wolters Kluwer acquired FRSGlobal, a financial regulatory reporting and risk management firm.

The company acquired SASGAS, a provider of financial reporting software to banks in China, in October 2011. That December, Wolters Kluwer acquired Medknow, an open access publisher. Also in 2011, Wolters Kluwer sold its pharmaceutical industry-related Marketing and Publishing Service division to Springer Science+Business Media, which led to a workforce reduction at its facility in Ambler, Pennsylvania, eventually leading to the site's closure in 2013.

In 2012, Wolters Kluwer acquired Acclipse, an accounting software provider, and Finarch, makers of a platform for financial institutions to manage data, compliance, and risk. The company's health division tested technology to identify and treat sepsis in December. Wolters Kluwer acquired Health Language, a medical terminology management provider, in January 2013. In May 2013, the company acquired Prosoft Tecnologia, a Brazilian tax and accounting software provider. It also acquired CitizenHawk, an American online brand protection and global domain recovery company, in September 2013. That same month, Wolters Kluwer acquired Svenson, an Austrian regulatory reporting provider. This acquisition enabled both companies to assist Austrian banks and insurance companies in meeting national and international regulatory requirements.
