There’s a funny story behind this post. My stomach was growling and I thought “Hmmm, what if there was a device where you could hook up to your body parts and see what’s going on in there??” Like, say your stomach hurts or you’re hungry or your leg is in pain, you could hook up to some technology screen type deal and see what is causing those changes. OK, you may already know but I mean in a way where you could see it .(medical genuis smarty pants lol) You can go to the doctor and already know what needs to be done. Anywho, that’s when I thought it would be fun to look at some inventors / inventions that we may not have known about.
The Pencil Sharpener

Also, known as The Love Sharpener, The Pencil Sharpener was patented by a black man named John Lee Love. John did not invent the pencil sharpener* but what he did invent would carry on to the same pencil sharpeners we use today. A carpenter in Fall River, Massachusetts, John invented several devices and in 1897, he patented a portable pencil sharpener known as the “Love Sharpener.” (*The first ever pencil sharpener was patented in France by mathematician Bernard Lassimone in 1828. A decade later another Frenchman, Therry des Estwaux, designed a conical-shaped device that, when a pencil was inserted and twisted, all sides of the pencil were whittled away at once and make the sharpening process much quicker.).
Heating Furnace — Ventilation System
Alice H. Parker, an African-American woman from Morristown, NJ developed, in 1919, an early concept of the modern home heating system. Her system gave birth to the thermostat and the forced air furnaces in most homes today, replacing what was then the most common method for heating – cutting and burning wood in fireplaces or stoves. Parker’s invention would be better known today as Central Heating.
The Mailbox
What would you know, a black man invented the mailbox. Known as The Street Letter box back then, Philip Downing designed a metal box with four legs which he patented on October 27, 1891. He called his device a street letter box and it is the predecessor of today’s mailbox. (A fellow blogger wrote a post about Downing awhile back. Check it out here!)
The Sanitary Belt, The Walker, The Toilet Tissue Holder

Before pads and tampons menstrual huts were common where women would be separated from communities while on their cycle (known biblically as a time of uncleanliness). Later women began using cloth or rags which is where the term “she’s on the rag” came from. Common forms of protection rabbit skins, rags, menstrual aprons (aprons??) homemade knitted pads and eventually, the sanitary belt. I heard of the sanitary belt from my mom, otherwise I would not have a clue what this is. Mary Beatrice Davidson Kenner, a black woman, had some pretty cool inventions, the Sanitary Belt being one of them. She also invented the walker and toilet tissue holder. Pretty neat. (Ladies, you can learn more about the evolution of the pad HERE.)
Toilet
Thomas Elkins, a black man, invented a lot of things (to include an improved refrigerator). Known then as a Chamber Commode, the modern toilet was patented by Thomas Elkins on January 9, 1872. Elkins’ commode was a combination bureau, mirror, book-rack, washstand, table, easy chair, and chamber stool. (The flush toilet goes back to the 1500s but the idea failed to catch on until later).
The First “Perm”

Did you know that Perm is short for Permanent? The first concept of the perm was invented by a black woman named Marjorie Joyner. The granddaughter of slave owner and slave, Marjorie developed an invention called “The Permanent Waving Machine” which permed or straightened hair by wrapping it in rods. Later, a black man named Garret Morgan (inventor of the Traffic Signal and Gas Mask) invented our modern version of the perm by accident. In his tailor shop, Garrett was thinking of a solution he could use to polish the needles to a high gloss and stop them from scorching clothes. When Morgan doctored this liquid, he decided to test the effects of the liquid on dog’s hair and saw how the texture had smooth out. Later trying this on human hair, the relaxer was born. Delighted with his success, Morgan coined his hair division the G.A. Morgan Hair Refining Company. This Company was also responsible for the black hair oil dye and the curved tooth iron comb (to be used as a hot comb.)
Blood Bank
Charles R. Drew was an African-American surgeon who pioneered methods of storing blood plasma for transfusion and organized the first large-scale blood bank in the U.S. Ironically, he died due to an accident that blocked blood flow to his heart (there’s a myth that he died at an all-white hospital among whites who refused to operate on him but this story cannot be verified. According to my research, Drew was treated at Alamance General Hospital, a facilities-poor “White” hospital. The White doctors at Alamance began work immediately but Drew’s injuries were so severe and his loss of blood so great that he could not be saved. It is possible that due his prominence he was treated better than most blacks were during the time but further research / insight is needed.)
Feeding Tube
Bessie Blount was a physical therapist who served during WWII. She invented an electrically driven feeding tube device that enabled wounded soldiers to consume a mouthful of food when biting down on a tube. At the time, it was hard to get a patent and she donated this invention to France. In 1951, she received a patent for a modified version from the U.S. called the portable receptacle holder, smaller tube that could be worn around the neck. However, many of Blount’s inventions are not very well known since she signed over her inventions to France.
