Erhard Ratdolt (born 1442 – died 1528) was an important early German printer. He was born in Augsburg, a city in Germany.

Ratdolt worked as a printer in Venice, Italy, from 1476 to 1486. After that, he moved back to Augsburg and continued his printing work there. From 1475 to 1478, he worked with two other German printers.

Erhard Ratdolt's Printing Innovations

Erhard Ratdolt was known for his clever ideas in printing. He made many improvements to how books looked and were put together.

Introducing Title Pages

One of Ratdolt's big achievements was helping to introduce the modern title page. The first book his printing group made was the Calendarium in 1476. This book, written by Regiomontanus, had one of the very first title pages we know of. A title page is the first page of a book that shows its title, author, and publisher.

Printing Geometric Diagrams

Ratdolt also solved a big problem for printers: how to print geometric diagrams. These are drawings with shapes and lines, like those you see in math books. He figured out a way to print them clearly. He used this skill in his 1482 edition of Euclid's Elements. This was a very famous book about geometry.

Other Important Books

Besides the Calendarium and Euclid's Elements, Ratdolt printed other important books. These included the Historia Romana by Appianus in 1477. He also printed the Poeticon astronomicon in 1482, which was about stars and planets. Later, he printed works by Haly Abenragel (1485) and Alchabitius (1503).

First Type Specimen Book

Erhard Ratdolt is also famous for creating the first known printer's type specimen book. This was like a catalog. It showed all the different fonts (typefaces) he could use to print books. This helped customers choose how their books would look.

Ratdolt's Influence on Printing

Ratdolt's new ideas for how pages were designed and the types of fonts he used were very popular. He was good at mixing different fonts with woodcuts, which are pictures carved into wood blocks. These pictures were then pressed onto the paper.

His style and technical solutions inspired other printers. For example, his work influenced William Morris, a famous British artist and printer who lived much later.
