The "inventor" of the whiteboard was Martin Heit, a Korean photographer who came up with the idea while developing photos in a darkroom. This photographer realized that he could use a marker on negative film. In this way, if you wiped a damp cloth over it, the marks were easily erased. Heit thought he could use this to put on the wall next to the phone and write 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 Dri-Mark company. 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 productDon't miss this video to take care of and make the most of your chalkboardhttps://youtu.be/sk6hqdOsDW0
