T is for E. Lillian Todd - Pioneer Women in Aviation: A-Z Challenge

E. (Emma) Lillian Todd 1865-1937
E. Lillian Todd remembered that she loved discovering how things worked as a child. She would disassemble toys, use scissors as a tool, tinker with weather vanes, typewriters, telescopes, and even her walking dolls. As she grew older, she learned to build airship models and other aeronautic toys with motors.

Lillian was born in Washington D.C. in 1865. From a census taken in 1870, it appears her father had either died or left the home. Lillian was living with her mother and sister alone, but later mentioned she inherited her "mechanical and inventive talent" from a grandfather.

Lillian's education is somewhat vague, but she was bright enough to learn how to type and land a job at the Patent Office (NY). Another job opened in the governor's office in Pennsylvania, where she was the first woman to receive an appointment in that state's executive department. Returning to New York in 1890, she studied law at New York University and was a member of the school's first Woman's Law Class. Still a tinkerer at heart, she managed to invent a typewriter copy-holder, sharing a patent with a colleague in 1896. During the Spanish-American War, she also worked for the Director-General of the Women's National War Relief Association as a secretary in 1898. She was 33.

After 1903, Lillian returned to her ongoing fascination with "mechanical and aeronautical toys." Not since the model-making days of her childhood had she ever seen more than a model, but witnessing live airships flying over London and at the 1904 Louisiana Purchase Exposition in St. Louis gave her ideas. When she saw a sketch of an airplane in a 1906 Parisian newspaper, Lillian knew it was time to build a new model.
1904 Louisiana Purchase World's Fair
In December 1906, Lillian proudly displayed her first airplane design as part of the Aero Club of America exhibit at New York's Grand Central Palace. Lillian was the first woman in the world to build and design a heavier-than-air aircraft. Lillian drew national attention as Miss E. Lillian Todd. Her display received the most visitors according to newspapers. Evening World (Dec. 4, 1906) reported that Andrew Carnegie (a wealthy philanthropist) had spent hours discussing the model with "Miss Todd." Whether he had considered becoming her patron is unclear. Indeed, money would be a factor building a full scale biplane. Olivia Russell Sage, a wealthy widow who had inherited millions and also admired the exhibit, became Lillian's patron, donating $7000 for the project.

In fall of 1908 Lillian hired two aeronautical engineers, Charles and Adolph Wittemann to begin construction. The plane would be built according to her design in Mineola, NY (inside a large shed). Meanwhile, Lillian pursued another interest, the mentoring and education of boys in the field of aviation. She formed the first Junior Aero Club of America in 1908. The club met in her living room, amidst all her inventions and models, where the group learned about flight and how to make models themselves. Clubs spread elsewhere and model making became quite the rage for awhile. The club also led to the formation of the Junior Wireless Club, which was a precursor to the Radio Club of America. 

"In Miss Todd's Living Room"


November 8, 1910 was the big day. Lillian's biplane had been rebuilt several times and finding the right engine was a fiasco, but the "Todd biplane" was finally ready. A crowd showed up at the Garden City Aviation Field to watch Didier Masson, a French pilot, fly Lillian's machine. The plane performed well. Masson flew for 20 feet, turned the plane around, returned and landed to everyone shouts of praise.

The top wing was modeled after wings of an albatross. Lillian spent hours studying  this bird at the museum. The frame was made of spruce, covered in bleached muslin and army duck, and held together with piano wire. Plane was 36 feet long.

She had invented, patented, and 
installed a device to control equilibrium. 

Lillian had planned to fly the biplane herself and wanted to travel around the United States, but the City of New York had denied her application for a permit to fly the previous year (Sept. 2009). Lillian was the first woman to apply for a pilot's license in the world.  

Interesting, the New York Times then reported two months later (Nov. 2009) that: "She intends to operate the machine herself as soon as her hands, which have given out, due to overstrained muscles and nerves, will allow of her managing the steering gear." 

Another newspaper several months later (Daily Journal and Tribune, Knoxville, TN, Jul 10, 1910) reported Lillian had signed up for several long-distance flights and that her mechanics were working on three designs. It appears that Lillian fully intended to fly the Todd biplane on her own, but something happened. Perhaps the City of New York intervened

No one knows for sure if Lillian ever flew her biplane. It's not likely she did. In 1911, she accepted a position with her benefactor Olivia Sage, and in 1912 arranged to have the biplane donated to the state of New York (the first person to do so). The Junior Aero Club thrived without her for many years to come and Lillian eventually settled in California in 1936. No one knows if she continued her experiments in aviation.  




Other Patents filed:

--cannon fired at noon by sun power
--sun dial
--aeolian harp device played by the wind

Celebrate the Small Things: Thankful for AC

W~h~e~w. Yesterday our outdoor thermometer registered 114.2 degrees. It's quite literally open the door here, step out onto
Our sturdy AC companion & back porch
herb garden (mums in front)
the porch for five minutes and slam the door again. We are sweltering here in eastern Washington, as is much of the Northwest. If this isn't global warming, please someone give me a different (intelligent) explanation. I think the argument is finally over.


We were briefly (4 am to 8:30 am) without air conditioning two days ago. It prompted a discussion on what we would do if it had lasted longer. We do have a generator attached to our camper, which means we could string an extension cord from there to our refrigerator in the house to keep the food frozen. That's a relief. We could also hunker down inside the camper and turn up the AC. None of that happened thankfully and with homes so well insulated these days, the house was a comfortable 75 degrees the entire time, but it does make you wonder how people managed before air conditioning. 

Sometimes you gotta laugh!

I have never experienced temperatures this high before, but do recall when AC in cars was an expensive option and a lot of us went without. If we had to travel in the heat, we relied on water, ice cubes in an ice chest, and towels over the windows. I can't imagine what it was like living down south in the U.S., but I read somewhere that air conditioning changed the deep south quite dramatically. 

One thing I've learned is that staying hydrated is critical, and that includes adequate intake of salt. With most of us concerned that too much salt is bad for us, this is one time when salt is a necessity. My husband lived in Turkey one year while in the Air Force. It was hot, arid and downright miserable at times. He remembers that salt tablets were dispensed at chow times and mandatory. I'm sprinkling salt in our water now. We started getting leg cramps (unusual for us) one day and I discovered online that this was possibly due to lack of salt. Well it worked....all cramping has stopped, and I'm a believer. Has anyone else experienced this?

Willis-Carrier-Inventor-Air-Conditioning
Willis H. Carrier (1876-1950)
 
Kudos to New Yorker Willis H. Carrier, who in 1902 invented the first modern air conditioner. Although few benefited from it at the time, this invention would help modernize the world and change the way we live. An interesting aside is that he struggled in school with learning mathematical fractions. His mother took on the challenge and taught him the concept by cutting up an apple. Willis later wrote that the lesson taught him the "value of intelligent problem-solving." I like that it also shows the power of a parent's influence :)  

In 1998 Time magazine listed Willis as one of the“100 Most Influential People of the 20th Century.” I couldn't agree more!


Happy Weekend!

R is for Rolling Pin: Inventions by Women A-Z

A magazine in 1891, Inventive Age, printed in its "New Patents for Sale" column the following:

"Catharine Deiner advertised the rolling pin for which she had received a patent only the month before. 'Improved rolling pin is for sale. It consists of a rolling pin with an adjustable sleeve, which when placed on the pin gives the operator four cake cutters, making in possible to rapidly cut up dough into cakes without waste. It can be used in bakeries and families.'" 


Now that is one complicated rolling pin. Take a look at the patent illustration itself, dated 1891 for Catharine Deiner of Lebanon, PA.

Catharine wrote in the patent: 

"My invention relates to an attachment to a rolling-pin, by which dough may be cut into various shapes and forms."

 So reading through the patent, I believe this is what she meant: 
  • Figures 6, 7 and 8 are the shapes and forms that can be cut.
  • Figures 2 and 5 show the cutter positions. 
  • Figure 4 is an end view of a zig-zag cutter.
  • Figure 3 is an end piece showing how it's fastened. 

Pretty complicated, if you ask me, but wouldn't it be fun to try one of these? I wonder if any still exist.

 Have you seen this rolling pin?

L is for Life Raft: Inventions by Women A-Z

Actors on a life raft - "Primitive Lover" 1922

Maria Beasley (1847-1904?) of Philadelphia (PA) wanted a better life raft, one that was "fire-proof, compact, safe, and readily-launched" when needed. According to the patent, she invented a new design in 1880.



Maria's life raft sported guard railings and rectangular metal floats, unlike typical rafts with hollow tube floats and zero safety railings. By changing the style of the floats, Maria's raft actually folded and unfolded more easily for use and storage, even with the added guard rails. It is not clear from the patent how she made the raft fire proof or why that was important. Life rafts were made of wood and metal in the 1800s, but it seems logical water itself would have been a huge deterrent to fire.

A typical life raft in 1874
(patent) Maria's life raft in 1880 had guard railings
Not much is known about Maria's personal life. From a census in 1880, she was reported as an unemployed housewife, but later, it is clear from other records she had become a successful inventor and business woman. At the Cotton Centennial Exposition in New Orleans in 1884, we know that she displayed some of her inventions, including an improved version of her life raft patented in 1882 

Maria actually made money from her inventions (15 to be exact). Some of her other inventions were:
  • foot warmer
  • steam generator
  • anti-derailment device for trains
  • wooden barrel-making machine
 Her wooden barrel-making machine (for wine-making and food preservation) is said to have made Maria a fortune. She earned close to $20,000 a year, while most working women in her day earned about $3 a day!

K is for Kevlar: Inventions by Women A-Z


Stephanie Kwolek (1923-2014)

Stephanie Kwolek wanted to be a medical doctor someday. After attending college and becoming a chemist, she accepted a temporary position at DuPont as a research scientist, hoping to save enough for medical school. Instead, DuPont offered her a permanent position and a promotion she couldn't turn down, changing the course of her life. 

Stephanie later said, "I think one of the reasons I've stayed so long is that back in 1946, women were only able to work in the laboratories for a few years, then they'd get pushed into so called women's jobs. I had something to prove and also the work was very interesting." 

We can be thankful Stephanie made a career at DuPont and had something to prove. In 1965, while studying long molecules at low temperature, in her search for a lightweight plastic that could be used in car tires (to possibly reduce gas mileage), she discovered a substance that was lightweight and incredibly strong. The discovery led to the invention of a synthetic material called Kevlar, which when tested, was 5 times stronger than steel out of water and 20 times stronger under water. It was also heat and corrosion resistant.  
Aramid fiber2.jpg
Kevlar® is a liquid, which is then 
converted into fiber that can be 
woven into a textile material. 

Since 1965, Kevlar has been used to strengthen and improve close to 200 products. Here are some examples:
  • skis
  • safety helmets
  • hiking and camping gear
  • suspension bridge cables
  • bulletproof vests (invaluable to law enforcement officers, police dogs, and soldiers in the field)
  • clothing (Kevlar is resistant to wear and corrosion)
  • fiber optic cables
  • firefighter suits (Kevlar is flame resistant)
  • fuel hoses
  • airplane parts
  • tires (radial; and racing car tires)
  • spacecraft parts
  • canoes
  • tennis racquets
  • rope  
 
 

Kevlar has made the world a whole lot safer by adding incredible strength (without added weight) to many, many products. Countless lives have been saved as a result of this invention.



Commenting on her discovery, Stephanie Kwolek said, “I don’t think there’s anything like saving someone’s life to bring you satisfaction and happiness.” She has received numerous awards for her research, including induction into the National Inventors Hall of Fame, an honor shared with other great inventors, among them, Thomas Edison, the Wright brothers, Henry Ford, Alexander Graham Bell, and Lewis Pasteur.

Brief History of the Stereoscope: Stereoviews A-Z


The Stereoscope is a special device used to view photos in 3-D. It was a popular form of entertainment in the U.S. from the 1840s to the 1930s, and also used as a teaching tool in classrooms for learning geography, natural history, world events and a wide variety of topics.

The invention was based on English scientist Charles Wheatstone’s research on binocular vision in the 1830s, and predates early photography. Wheatstone experimented with
Holmes Stereoscope
sketched drawings, but as knowledge of photography developed in the 1840s, the technique was applied to photos. The images were called stereographs (or stereograms) in the beginning, and later known as stereoviews.
 
Here is how the stereoscope works. Two identical photos, arranged side by side on card stock, are viewed through the stereoscope as two and half inches apart (or the distance between the eyes) through the viewer's lense/mirror hooded assembly (on left in picture). The eye sees a 3-D image.

It was not until the Great Exhibition in 1851 that stereoscopes and stereoviews became known to the general public. Queen Victoria in England was fascinated with the invention, and influenced its mass production. One company, the London Stereoscopic Company, sold half a million stereoviews between 1854 and 1856.

In the U.S., author and physician Oliver Wendell Holmes invented a hand-held stereoscope viewer in 1861 that was more economical. With further improvements by Joseph L. Bates (a Boston merchant), the Holmes viewer was soon a common item in Victorian homes all across America.

The stereoscope lost its appeal in the 1930s with the advent of silent film and radio. In the 1950s, it made a comeback with the ViewMaster, a type of stereoscope for children that can still be purchased in stores. And of course . . . there are 3-D movies and television today.
