History of Bean Day
The day commemorates the death of the geneticist Gregor Mendel, whose experiments with breeding pea plants formed the basis of modern genetics. From what we could find, it would appear that Paula Bowen is the creator of Bean Day. Her main reasons were that there aren't many holidays to celebrate around the time that Bean Day has typically been celebrated. Plus she thought that the world needed a day to honor Mr. Bean. Her father was a pinto bean farmer, so she's pretty familiar with beans in general and no doubt was raised on them. Beans are also healthy and common in many cuisines throughout the world, so we're not at all surprised that there's a day dedicated to their celebration.
Electronic greeting card websites seem to have a lot of references to Bean Day, but we're not sure if it actually means that e-card companies actually invented Bean Day or if they've just been the most effective at capitalizing on it. Small matter though if you hate beans and don't want to have anything to do with them on Bean Day, you can still send greeting cards to your friends to mark the occasion. Some people think that it's actually called National Bean Day', but there's no congressional record nor any presidential proclamation for such a day. So it's safe to assume that it's not an officially recognized occasion.
