Actually it is definitely known. Just takes a little extra research sometimes to figure something out if you want to know it bad enough. Mistery is right as well, Science is made up of millions (figure of speech, but probably true nonetheless) of useless facts that are impressive to know.

Kolliker described conspicuous "granules" aligned between the striated myofibrils of muscle, and Flemming observed "filaments" in the cytoplasm of other cell types. In 1890 Altmann discovered a method of staining these structures with fuchsin that made it possible to demonstrate their occurrence in nearly all types of cells. He interpreted them as "elementary living particles, bioblasts, present in all cells", considering them similar to bacteria and probably capable of independent existence. The term mitochondrion, descriptive of the prevailing threadlike form of the organelle, was introduced in 1898 by Benda, who made valuable observations on their form and distribution in preparations stained with alizarin and crystal violet.
