The "inventor" of the whiteboard was Martin Heit, a Korean photographer who got the idea while developing photos in a darkroom. This photographer realized that he could use a marker on the film negatives. This way, if you wiped a damp cloth over it, the marks would erase easily. Heit thought he could use this to put on the wall next to the phone and jot down messages there. Heit thus created his first whiteboards using film negatives. The photographer was preparing to present his invention when the event venue burned down the night before the premiere. As a result, Heit decided to sell his idea to the company Dri-Mark. Thus, instead of promoting it as a device for taking telephone messages, he introduced the new whiteboard to the world of education. In the 1960s, the first whiteboards went on sale. Unfortunately, they were not very popular, partly because they were very expensive. **Images may be references and examples of the product Don't miss this video on how to care for and make the most of your chalkboard https://youtu.be/sk6hqdOsDW0
