A Brief History of Ravensburger Puzzles
The Founding of Ravensburger
In 1883, Otto Maier, a bookbinder from the city of Würzburg in Bavaria, Germany, founded a company that would eventually become one of the world’s leading puzzle manufacturers: Ravensburger. Maier named the company after his hometown, which was also known as “Ravensburg” in English. The company started small, producing high-quality maps, globes, and atlases for schools and institutions. However, it wasn’t until the early 1900s that Ravensburger began producing puzzles.
In 1900, the company introduced its first puzzle, a 1,000-piece map of the world. This was followed by a series of increasingly complex puzzles, including jigsaw puzzles and other types of brain teasers. Over the years, Ravensburger’s reputation for producing high-quality, challenging puzzles grew, and the company became a household name in Germany and beyond.
Today, Ravensburger is still family-owned and operated, with over 130 years of experience in the puzzle industry. The company continues to innovate and create new and exciting puzzles, while maintaining its commitment to quality and attention to detail.
The Evolution of Ravensburger Puzzles
Ravensburger has been in the puzzle business for over a century, and their dedication to quality and innovation has been the driving force behind their success. From their humble beginnings as a family-owned business to their current status as a global brand, Ravensburger has always been at the forefront of the puzzle industry.
In the early 1900s, the company began producing wooden puzzles, and quickly gained a reputation for their high-quality products. Over the years, Ravensburger expanded their product line to include jigsaw puzzles, puzzle boards, and other accessories.
One of the key factors that sets Ravensburger apart from their competitors is their commitment to creating puzzles that are both challenging and enjoyable. They use a unique design process that involves a team of artists, puzzle designers, and engineers to create their puzzles. This collaborative approach ensures that each puzzle is carefully crafted to provide a unique and engaging experience for puzzle enthusiasts of all levels.
Another important aspect of Ravensburger’s success is their focus on quality. They use high-quality cardboard and printing techniques to ensure that their puzzles are durable and long-lasting. They also use a special “soft-click” technology that makes it easier to connect the pieces together without damaging the image.
In recent years, Ravensburger has continued to innovate and expand their product line. They have introduced a range of themed puzzles, including puzzles based on popular movies, TV shows, and video games. They have also developed a line of 3D puzzles that allow puzzle enthusiasts to create models of famous landmarks and structures.

Finally, Ravensburger’s commitment to quality is reflected in its willingness to innovate and push the boundaries of what a puzzle can be.

These innovations have helped to make Ravensburger puzzles accessible to a wider audience and have contributed to the company’s reputation for producing high-quality, innovative puzzles.
