Richard Altmann
Richard Altmann improved cell fixation methods using osmium tetroxide and potassium dichromate and along with a staining technique and heat to find filaments developed from granules. He named these granules 'bioblasts' which he claimed had metabolic and genetic autonomy. His explanation of these 'bioblasts' gained great criticism and skepticism because scientists had not found how cells made energy or even knew what ATP was. Today, these 'bioblasts' are known as mitochondria. His true curiosity and integrity in his work led other scientists to study organelles more and provided scientists with early morphology of mitochondria.
