Berlitz Corporation is a language education and leadership training company which is based in Princeton, New Jersey.

Berlitz Corporation is owned by Berlitz Holdings, a company established through a 100% investment by ILSC Holdings LP (which owns ILSC Education Group, a company engaged in language education businesses such as study abroad), with more than 547 company-owned and franchised locations in more than 70 countries.

However, due to illness, Berlitz asked Joly to take over his classes, and teach by pointing at objects, repeating the French word for them, and acting out verbs.

[5] In the 1950s, Berlitz opened its first Latin American language center in Mexico, followed by locations in Brazil, Venezuela, Argentina, Colombia, Chile, and Peru.

[6] In 1966, Berlitz became a subsidiary of Macmillan, Inc. Robert Strumpen-Darrie continued as president until his retirement in 1970, Raphael Alberola became CEO for about 4 or 5 years and then Elio Boccitto led the company through most of the 1980s.

[6] On August 19, 1992, Berlitz International Inc. announced it had signed a definitive agreement to sell a 67 percent stake to the Fukutake Publishing Company, with the merger to be completed by the end of the year.

Today, there are a variety of derivative methods and theories that found their beginnings in the natural and communicative elements that were pioneered by Berlitz.

In November 2010, management attempted for the first time to claw back the employee gains of the past 30 years in order to substantially reduce the conditions guaranteed in the collective bargaining agreement, threatening to lay off up to half of the contract teachers if the givebacks were not agreed to.

[31] Berlitz filed suit against the union for damages it says it suffered during the strike, but the claim was rejected by the Tokyo District Court on February 27, 2012.

[34] In 2010, employees of Berlitz language centers in Germany experienced a major labor conflict, as management planned to lay off nearly 70 contract teachers in order to economize with a staff of freelancers.
