Laura Scudder (1881 - 1959): Potato Chip Packaging Pioneer

Posted May 10, 2012 12:00 AM by SavvyExacta

Did you ever eat Laura Scudder's Potato Chips - "the noisiest chips in the world"? They are "just like you remember!" Scudder started a food company in 1926 after careers as a nurse and an attorney. While she studied for the bar exam, she and her husband ran a restaurant. They later ran a gasoline station. Her food company produced potato chips and later, peanut butter and mayonnaise. Her innovations in packaging helped potato chips to become a mass market product.

Early potato chips were packaged in barrels or tins. The chips at the bottom of the containers were often stale and crumbled.

Scudder asked her female employees to take home sheets of wax paper and iron them into the shape of sealable bags. This was her first innovation in potato chip packaging. Cellophane was invented by a Swiss chemist in 1912. A moisture-proof version, manufactured by Du Pont, became available in America in 1927. Use of cellophane as potato chip packaging further increased the freshness and crispness of the chips.

Laura Scudder's was the first company to place freshness dates on food products. The date helped ensure that the product would live up to its reputation as the noisiest (crunchiest and freshest) chips in the world.

Despite her determination, Scudder faced many obstacles as a woman entrepreneur during the Great Depression. Male insurance agents turned her down when she searched for a policy for the company's sole delivery truck. They thought a woman would not reliably pay the premiums. Scudder found a female insurance agent and insured the company's fleet as it grew.

Laura Scudder's had 1,000 employees and 50% of the potato chip market in 1953. Scudder turned down a $9 million offer for the company when the potential buyer wouldn't guarantee employees' jobs. She sold the company for $6 million to a more agreeable buyer in 1957. Today, her peanut butter line is marketed by Smucker's and her potato chips are marked by Shearer's Foods.

Frances Ashcroft: Award-Winning Diabetes Researcher

Posted April 26, 2012 12:00 AM by SavvyExacta

Professor Frances Ashcroft discovered a link connecting an increase in blood sugar to the secretion of insulin in 1984. She also found a genetic mutation that causes neonatal diabetes. Children suffering from this form of diabetes can now be treated by pill rather than injection thanks to Ashcroft's work.

Educated at Cambridge University, Ashcroft holds BA, PhD, and ScD degrees. She is the Royal Society GlaxoSmithKline Research Professor at the University of Oxford. Her main areas of research include insulin secretion, type 2 diabetes, and neonatal diabetes. She authored a text book, Ion Channels and Disease.

Ashcroft discovered the ATP-sensitive potassium channel in 1984. The channel allows potassium ions to move out a cell. The channel is closed when glucose breaks down - stimulating insulin secretion. This was the missing link connecting glucose to insulin secretion.

In 1995 Ashcroft was part of a team that discovered the DNA sequence for the ATP-sensitive potassium channel. DNA screening enables people to determine if they have a common gene variant that causes an increase in the risk for type 2 diabetes.

Further research in 2003 led to the discovery of a mutation in the channel that can cause neonatal diabetes. It can be treated by sulphonylurea drugs. Treatment in pill form improves the quality of life for many diabetes patients; previously treatment was limited to injectable forms.

Ashcroft was named European Laureate at the L'Oreal-UNESCO For Women in Science Awards on March 30, 2012. The awards are presented annually and there is one winner from each major continent. Today Ashcroft's studies focus on obesity.

Willa Brown Chappell (1906-1992): Pilot and Trainer of Tuskegee Airmen

Posted March 29, 2012 12:00 AM by SavvyExacta

Willa Brown Chappell became the first African-American woman to earn a commercial pilot's license. She helped train approximately 200 pilots who went on to be known as "Tuskegee Airmen" who flew in WWII.

Education and Early Career

Chappell graduated from Indiana State Teachers College with a degree in education. She earned a master's degree in 1938. Her flight training began in 1934 at Chicago's Aeronautical University. Chappell passed the exam with a score of 96%. She earned a master aviation certificate, commercial pilot's license, instructor's rating, and radio license by 1939.

Chappell worked as a school teacher before most of her time began to revolve around flight. She taught commerce at Roosevelt High School in Gary, Indiana.

Pilot and Instructor

In 1939 she was a federal coordinator of civilian pilot training. She founded the National Airmen Association of America. The mission of the organization was to encourage African Americans to join the U.S. Air Force.

With Lieutenant Cornelius R. Coffee, whom she married, she started the Coffee School of Aeronautics. More than 200 of the students trained in the program went on to fly in WWII and were known as the Tuskegee Airmen. This group flew with distinction despite racial discrimination.

Chappell became the first African American officer in the Civil Air Patrol (CAP) when she was promoted to the rank of Lieutenant. She was the federal coordinator of the Chicago unit of the CAP civilian pilot training program.

Chappell added another record to her name, becoming the first woman in the U.S. to have both a commercial pilot's license and a mechanic's license in 1943.

Thelma Estrin (1924-): First Female IEEE President

Posted March 08, 2012 12:00 AM by SavvyExacta

Thelma Estrin was an early pioneer in the application of computer technology to healthcare and medical research. She later became a professor at a number of colleges including the University of California at Los Angeles (UCLA). Estrin was president of the IEEE Engineering in Medicine and Biology Society and vice president of the IEEE.

Education and Early Career

Estrin, pictured at the center of the top of the photo, was born in New York City. She originally studied accounting and history in college; her mother thought she would wind up a lawyer. That changed when her husband entered the U.S. Army during World War II. Estrin took a three-month engineering course and began working at Radio Receptor Company. She built electronic devices, working first as a machinist and then as an electronic technician.

After the war, she obtained her BSc, MSc, and Ph.D in electrical engineering from the University of Wisconsin - Madison. Her husband attended the same college at the same time. His education was financed by the GI Bill; Estrin sold her deceased mother's engagement ring to help pay her bills.

Computers and Biomedical Engineering

In 1951, Estrin's husband obtained a job back on the east coast. Estrin found her own job in the electroencephalography department at New York's Columbia Presbyterian Hospital Neurological Institute. At the hospital she developed an interested in biomedical engineering when her colleagues were interested in measuring the action potentials along the nerve fiber. She redesigned a frequency analyzer to examine EEGs quickly and accurately.

A physicist visited the institute where Estrin was working. He was interested in learning about computers so he could build one for Israel. Estrin's husband received a fellowship to go to Israel to build a computer and they both--with their young daughter--sailed there in 1953. Estrin helped redesign the computer's adder and multiplier, improving reliability by using newer vacuum tubes.

When Estrin's husband got a job on the faculty of UCLA she was unable to find work there because it was considered nepotism. She joined the faculty of a junior college in San Fernando Valley, CA teaching drafting. Through a colleague Estrin joined the Brain Research Institute (BRI) in 1960 and became director of its Data Processing Laboratory. She published 50 technical papers on the use of computing technology in healthcare. She also provided support for research projects by promoting the use of computers and helping scientists use computers to solve problems.

Estrin received an appointment to the anatomy department and eventually to the computer science department at UCLA. She also served as president of the IEEE Engineering in Medicine and Biology Society. She was the first woman elected to national office as vice president of the IEEE.

Introduce a Girl to Engineering Day: February 23, 2012

Posted February 22, 2012 12:00 AM by SavvyExacta

Organizations including Northrop Grumman, GE Healthcare, Boeing, and Raytheon (and many more!) are planning to participate in Introduce a Girl to Engineering Day on February 23. The events will introduce girls in middle and high schools to engineering and show them how math and science can be fun. Games, discussions about career choices, and critical thinking and teamwork activities are just some of the things that are planned.

From the National Engineers Week Foundation website:

"For the past eleven years, women engineers have introduced more than one million girls and young women to engineering. More than just one day, Introduce a Girl to Engineering is a national movement that shows girls how creative and collaborative engineering is and how engineers are changing our world."

Relatively Few Women Pursue Engineering in College

Although women accounted for 55% of all college undergraduates in 2004, they made up just 20% of the undergraduate engineering population. The number of female engineering graduates fell by 5.2% from 2004-2009. (The number of male engineering graduates rose by 11% during that time period.)

Many of those who do pursue engineering in college are successful. Stanford University's top 5% graduating engineering students were evenly split between males and females. The females, however, made up just 27% of the total number of graduates in engineering disciplines.

SAT Performance Doesn't Indicate Engineering Interest

It seems that such programs as Introduce a Girl to Engineering Day are key in gaining girls' interest. According to a 2010 study, boys outperformed girls in a standardized math exam (at age 13) by 13:1. Today it's closer to 3:1. So why are there so fewer girls who go on to pursue engineering? It could be that societal factors have a role and encouragement could help push through those barriers.

Do you encourage the younger generation to think about engineering?

Olive Dennis: Rail Travel Improvements (1885-1957)

Posted February 16, 2012 12:00 AM by SavvyExacta

Olive Dennis held several positions at the Baltimore & Ohio (B&O) Railroad. She began her work as a draftsman in 1920 and went on to make changes to the design of passenger cars.

Railroad Passenger Improvements

Dennis began working at the B&O Railroad as a draftsman in 1920. At that time she helped design bridges. Railroad executives saw another need for her in a different area of the industry.

Rail travel during Dennis' time was hot, dirty, smelly, and uncomfortable. She was soon promoted to the position Engineer of Service and focused on improving passenger service. The railroad wanted to keep the support of female passengers as rail travel became more common. (She later held other positions and had a 30-year career.)

Dennis' suggestions included:

  • New ventilation system (patented as the Dennis ventilator) allowing passengers to let fresh air in through the windows - trapping dust at the same time
  • Air-conditioned compartments
  • Improved lighting by dimming the overhead lights at night
  • More comfortable seats that reclined and had stain-resistant upholstery
  • Redesigned restroom facilities to be more practical and that were stocked with paper towels, soap, and drinking cups
  • Coach car lunch counters
  • Sleeper service
  • Designed a state-of-the-art, high-speed luxury train known as the Cincinnatian

Education and Early Career

Dennis was born in 1885 and grew up in Baltimore, MD. After graduating at the top of her high school class she was awarded a full scholarship to Goucher College.

  • 1908 - Earned a Bachelor of Arts degree from Goucher College
  • 1909 - Earned a Masters degree in Mathematics from Columbia University
  • 1920 - Earned a Civil Engineering degree from Cornell University

After earning a mathematics degree, Dennis taught math in Baltimore. Her teaching career lasted for about 10 years. She returned to study civil engineering and became the second woman to graduate from Cornell University with this degree.
