Amanda Siebert wasn't always the jiggly Jolly Irene. Born in Jersey City, New Jersey, she was quite normal for the first twenty-one years of her life. In 1901 she weighed a respectable 120 pounds and gave birth to a child. Not only was a baby born, but because of a few glands gone awry, so was Jolly Irene.

The pounds piled up and the flesh got fleshier. Diets were ineffective, leaving her helpless against her newly acquired mass. One reporter later described her as having "biceps three times as large as Jack Dempsey." But at 620 pounds, rather than box the heavyweight champion, she turned her tragedy into profit by joining Ringling Bros.

A principle object of the present invention is to provide a greenhouse helmet designed to contain plants secured within and the helmet worn completely over the head of a person so that the person can breathe in the oxygen given off by the plants.

Another object is to provide a greenhouse helmet that has air filters so that ambient air containing carbon dioxide will be filtered therethrough and mixed with the carbon dioxide breathed out by the person to be used by the plants.

An additional object is to provide a greenhouse helmet that will contain hearing and speaking devices so that the person can hear within and speak out through the helmet.

A further object is to provide a greenhouse helmet that is economical in cost to manufacture.

A still further object is to provide a greenhouse helmet that is simple and easy to use.
