everybody doctor Oh miss Faye I want to cover two more historical figures so we have Anton or Anthony Van Leeuwen hook who just quickly is credited with creating the microscope that was first able to visualize microbes and then we have Robert Hooke and you'll see that he he's kind of the father of the origin of the cell theory so we'll dive in a little more detail there but that's kind of the basics of these two so this here is Anthony van Lew and Hooke and let me go ahead and show you his microscope that's more important so this looks like nothing but you have to understand this guy he was not a scientist he was not educated I believe he was a janitor and ran a dry goods store I think they called it a haberdashery but he was a master at grinding lenses so this is an example of a simple microscope there's just a single a ball like lens in the center of that but it's we don't know exactly for sure but the magnification on his microscopes was probably somewhere in the neighborhood of 270 to 400 X which 400 X as as far as we can get on our on our compound microscopes today without using immersion oil so pretty amazing so he was not that one I trust very very clear he was not the first person to create microscopes there were scientists and quote-unquote experts that were designing designing microscopes but no one could reproduce what he did so I find a kind of interesting so we'll compare him to Robert Hooke and he was actually the you know these national you know countries and and scientific organizations sent him to task to create microscopes and he did create very good microscopes but he couldn't reproduce what Anthony Van Leeuwen Hooke was doing so so he this guy he I get it's also kind of interesting and he wasn't a scientist because scientists of the day we're doing some strange things right they were doing tests on ground unicorn horn and things like that so sometimes it's better to kind of look at things from the outside so he was he was a different character when he used one these microscopes he would leave the specimen on it and you just make another one so he made hundreds of these microscopes he never let anyone touch them he never let anyone use his favorites so he would basically use them and then make a new one and these kind of things but so but he was but imagine being this man that every time he looked through his microscope he was the first human being to see it we had no idea what was going on around us and until he showed up as far as some he first saw things like animals or what he called animal cules or wretched beasts in rain water he loved looking at tooth scrapings he was the first person to ever see a human capillary or at least capillary beds he discovered human sperm so anytime he looked through his microscope he was probably the first human being to ever see it and that's pretty that's pretty amazing so that's Anthony van Lewin hook and his simple microscopes us remember he did not have meant the microscope he invented the first microscope that could actually see the microbial world alright and then we do have Robert Hooke so here's Robert Hookes microscope much more complicated this is a compound microscope like the ones that we use in lab remember compound microscopes have multiple lenses in them and he could see amazing things but nowhere near would Anthony van Lewin hook so he let me show you an example of what he saw so this would be some cork cells that he was looking at so he is giving given credit for being the father of the cell theory so let me tell you the two parts the cell theory the cell theory says number one all living things are composed of cells and number two all cells come from pre-existing cells so this might not sound like a very big deal but you have to understand the time they were in they didn't believe this will do I'll do a separate video about this but they believed that life came from nothing came from a life force not from pre-existing life so he's given credit for being the father of a cell theory but I also have to make it clear that the cell theory was not proven by him he discovered cells he called themselves these little boxes this is cork actually so he he discovered the cell or named the cell but the cell theory itself was proven much later but I still want you to know that he's the father of the cell theory so that's Anthony Van Loon hook the creator of the first microscope that could see the microbial world and in Robert Hooke the father or originator of the beginning at least of the cell theory I hope this helps have a wonderful day be blessed
