The Top Eight Women Inventors

Man does not have a monopoly on inventions.  It just seems that way because Mr. Bell, Mr. Jefferson, Mr. Franklin and Mr. Edison have been hogging all of the publicity the last 250 years or so. In fact, several women have made significant contributions to industry, the home, science and information technology.  Some were the first to contribute to their particular field and forge new accomplishments for others to advance.  If it weren’t for these women on this list, life would be more difficult today in many ways.


  1. Hedy Lamarr (1913-2000)  She is best known as movie star actress during the WWII era.  She starred in “Samson and Delilah”, “Algiers” and many others.  She also wanted to contribute to the World War II effort by figuring out how to prevent the jamming of and intercepting of frequency communication systems by the enemy.  She and her co-inventor, George Anthiel, figured out the technique of “frequency hopping” or what they call today, “spread-spectrum” communication, proving that she was not  just a pretty face for the movies.  This technology is used today for everything from military weapons to cell phone transmissions.  They received a patent for it but it didn’t earn her any significant wealth.  In 1997 she was awarded the Electronic Frontier Foundation (EFF) Pioneer Award.


  1. Sybilla Masters (died 1720) She was a significant contributor to the field of farming and weaving.  Masters was the first recorded American woman inventor.  She earned a patent for “Cleansing, Curing, and Refining of Indian-Corn Growing in the Plantations” and for a new methods for weaving straw for hats and bonnets. However, her husband had to put his name on the patent because of the laws at the time in 1715.  She deserves credit now for not being recognized back then.


  1. Josephine Garis Cochran (1839-1913) The world’s population owes this woman a collective thank you.  The reason?  She invented the first      working automatic dishwasher in 1889.  It was first shown at the 1893 Chicago World’s Fair.  The next phase for anyone out there, of course, is an automatic loader and un-loader.


  1. Marion Donovan (1917-1998) She invented the first waterproof, disposable diaper in 1950. The key word is “waterproof”.  Amazingly, business leaders weren’t interested in this at first, which showed an incredible lack of understanding to the plight of their wives and mothers.  She wasn’t discouraged.  She started her own company, Donovan Enterprises, and then sold it for a million dollars later.  At last the sweet smell of success!


  1. Grace  Murray Hopper (1906-1992) An engineer, educator and a naval officer rising to the rank of Rear Admiral, every computer programmer owes a debt of gratitude to her.  She invented  the concept of compiling programming languages. She popularized the term, “debugging” which refers to a weeding out code errors in a program.  She is a legend in the Navy and in the fields of Mathematics and Computer Engineering.

  1. Ada Byron, Lady Lovelace (1815-1852) She was a mathematician and a collaborator with Charles Babbage, the inventor of the Analytical Engine, who built the first mechanical computer that could calculate numbers.  She also foresaw that computers could do more than calculate numbers, such as composing music, creating graphics and would be used for practical and scientific use. She also wrote the first computer program (Bernoulli numbers) for calculating numbers for Babbage’s machine. She was indeed a pioneer and a profit of the computer age.


Marie Curie

  1. Marie Curie (1867-1934) Here is a woman who literally put her life on  the line for science. She was a polish physicist and chemist who      discovered radioactive metals such as Radium and Polonium.  She also discovered that the harmful properties of x-rays could kill tumors.  She made a decision to not seek patents for methods of processing  radium or how it could be used for medical applications. Curie was the first person to win two Nobel Prizes. She died of Leukemia caused by overexposure to radioactive material during her years of research.



  1. Lillian Moller Gilbreth (1878-1972) She was a pioneer in the field of ergonomics as well as an author, industrial engineer and inventor.      Gilbreth invented several helpful items for the kitchen to make our lives easier.  Everyone should give a collective bow of thank you (she saved our backs) to her because she invented the trashcan with the foot-pedal lid-opener.  She conducted several significant Time and Motion studies that simplified and improved industrial work. She also determined that stress affected worker efficiency as well as lack of sleep. While working for General Electric she conducted interviews with women to determine the proper height for stoves, sinks and other kitchen appliances.

The Chernobyl Disaster and Fukushima Accident

by Rick Bretz

Nuclear power has the ability to create energy, liberate countries from other energy sources like coal, oil, and water, and therefore pull a nation’s struggling economy forward after years of lagging behind other nations.  In the process, the same nuclear power source can produce tension between players on the world stage as North Korea and Iran are doing today or force every global leader to deal with a disaster and the environmental fallout that leads to an energy policy debate about the viability of nuclear reactors. Nuclear energy has positives and negatives but the one point every one agrees with  is that nuclear accidents are devastating to the environment and can wipeout entire city populations if the fallout isn’t controlled.   As with any new technology, the process and procedures continually evolve.  Engineers learn from design flaws and build systems that have better fail safes.  Operator training improves as scientists and political leaders develop better ways to handle the unique challenges of running nuclear power centers.

The following is a comparison of how two disasters were handled.  Research indicates that Chernobyl and Fukushima have both been labeled “Accidents”.  I prefer to call Chernobyl a “Disaster” because several lives were lost.  Fukushima should be labeled an “Accident” because no loss of life has been documented from it.  The lives were lost due to the Tsunami.  The chart below shows how the two governments handled the crisis, and more importantly, how much Japan may have learned from other nuclear problems, including the United States’ own nuclear accident, “Three Mile Island.”

                                                                                A Comparison

Chernobyl Nuclear Disaster Fukushima Nuclear Accident
Year of accident -1986 April 26 Year of accident –11 March 2011
Reason for Accident-Flawed reactor design. Power surge. Lack of communication between operators and Soviet government Reason for Accident-Earthquake followed by Tsunami,  generators on bottom floor. Lack of countermeasures based on current scientific research.
Inadequately trained operators Failure of imagination by designers and engineers
Active reactor sustained steam explosion followed by second explosion Partial reactor meltdown and loss of power to cooling systems   after  8 hours
Radioactive fallout-the radio nuclides reached as far as Britain and   contaminated large areas of the Soviet Union, including Belarus, Ukraine, and   Europe. Radioactive fallout-The Chernobyl accident released 10 times more   material into the atmosphere than the Fukushima accident.
Immediate casualties-50 people died immediately from radiation   poisoning that includes the first responders (fireman, helicopter pilots,   soldiers and miners) Immediate casualties-21 plant workers have been affected by radiation   sickness.  Several thousand people   died from the Tsunami.
Long term casualties unofficially in the thousands, still assessing. Long term casualties-No radiation linked deaths have been reported,   still assessing
Environmental Impact-livestock, vegetation, top soil, the surrounding   communities and fallout that was moved by the atmosphere to surrounding   countries Environmental Impact-More than 70,000 people have been evacuated   within a 12 mile radius of the plant.
Health Impact-4,000 children and adolescents contracted thyroid   cancer soon, 4 died. Health Impact-Still being monitored.
Immediate Public Information-Information about the severity was   withheld from the public for several days Immediate Public Information-Public was informed and evacuated as   soon as possible after Tsunami
IAEA Severity Level-7 IAEA Severity Level-Initially set at 5 and then raised to 7
Several years before area will be habitable Several years before area will be habitable

There are websites devoted to the analyzing what went wrong and how the fallout from Chernobyl affected the surrounding towns.   YouTube has several documentaries devoted to how the nuclear disaster was handled by the Soviet government. What is interesting about each accident is the way information was publicized to local towns and to the workers dealing with the problems.  It is study in how risk and crisis communication affected the aftermath of each accident.

The Chernobyl disaster became more of disaster because officials did not tell primary people in government the severity of the problem.  Therefore, they could not make decisions about moving people from the local area, specifically the town of Pripyat, near the Chernobyl plant where most of the reactor’s workers lived with their families.  I took several days before the families were moved from the area. Six hundred workers answered the call or the order to clean up the nuclear debris after the explosion as well as pour sand and boron from the air by using helicopter flying over.  All the while, pilots and other workers were absorbing massive amounts of radiation.  According to the NRC, the Nuclear Regulatory Comission, 600 workers initially worked at the site immediately after the accident. Among those, 134 had radiation sickness.  Of these, 28 died within the first four months of the disaster. In addition to the pilots who were hovering and flying over the reactor for long periods, miners were brought in to dig a tunnel underneath the reactor where a concrete sarcophagus would eventually be built.  The miners were not told how much danger they were near when digging the tunnel right underneath the disabled reactor. The Chernobyl disaster is a testament to how people can answer the call.  The Soviet era miners who are still alive to tell the story have commented in documentaries on the subject that who else would have been able to do it but us.


The Fukushima accident was caused by an Earthquake and the resulting Tsunami which caused the meltdown of three reactors from the loss of power to the generators. This is different from a power surge that caused the Chernobyl disaster.   Two different paths of communication exist when accidents and natural disasters occur.  One is crisis communication that originates from the government and local agencies through the use of corporate media to the citizens affected by the natural or man made disaster.  The other is risk communication that relies on the layers of government and other agencies to pass on vital information so decisions can be made and the public alerted.  The Soviet government failed on many levels pertaining to Chernobyl while the communication process from the Japanese government to various affected groups performed better during and after the Fukushima crisis.  Informing the public and making the decision to move citizens within the danger zone out of the area is one aspect of the disaster that went relatively smoothly, considering the Japanese government was also dealing with the damage done by the Tsunami.

Nuclear power is here to stay.  The challenge is to learn from the past while having enough imagination to think about future problems and put measures in place to prevent any accidents or disasters that may have dire consequences.
