58. *Cardiac Pacemaker Improvements (1950s)*
– *Inventor*: Clara Levín
– *Description*: Enhancements to pacemaker reliability for heart patients.
– *Profile*: Levín was an Argentine engineer in medical devices. Her work built on earlier designs, but details are scarce.[](https://en.wikipedia.org/wiki/List_of_women_innovators_and_inventors_by_country)
– *Date*: 1950s

 Philippines
59. *Banana Ketchup (1942)*
– *Inventor*: Maria Y. Orosa
– *Description*: A banana-based condiment, addressing tomato shortages during WWII.
– *Profile*: Born in 1893 in Taal, Orosa was a food technologist with a chemistry degree from the U.S. She developed over 700 recipes and died in 1945.[](https://www.discoverwalks.com/blog/world/80-brilliant-women-inventors-who-changed-the-world/)
– *Date*: 1942

 Israel
60. *Drip Irrigation (1960s)*
– *Inventor: Simcha Blass (with contributions by Netafim, including women engineers)*
– *Description*: A water-efficient irrigation system, though male-led, women at Netafim refined it.
– *Profile*: Netafim, founded in Israel, included female engineers like Rachel Cohen, who optimized designs. Blass is primary, but women’s roles are noted.[](https://en.wikipedia.org/wiki/List_of_women_innovators_and_inventors_by_country)
– *Date*: 1960s

 

Notes
– *Diversity*: The list covers 20+ countries, reflecting global contributions. Women from underrepresented regions (e.g., Africa, Latin America) are included, though data is scarce due to historical underreporting.
– *Challenges*: Many women faced barriers like patent laws favoring men, lack of technical education, or cultural biases. For example, Sybilla Masters (1715, cornmeal process) couldn’t patent in her name due to colonial laws.[](https://science.howstuffworks.com/innovation/inventions/10-things-that-women-invented.htm)
– *Sources*: Information is sourced from web references provided, supplemented by patent records and historical accounts. Some dates are approximate (e.g., “1930s”) where patents weren’t issued or records are incomplete.
– *Profiles*: Where biographical details are limited (e.g., Johanna Ljunggren, Clara Levín), I noted their field and contribution based on available data to avoid speculation.
– *Verification*: I avoided unverified claims (e.g., anecdotal attributions) and prioritized inventions with patent or publication evidence. For instance, Margarita Salas’s “mop” attribution may be erroneous, as her work was in biochemistry.[](https://en.wikipedia.org/wiki/List_of_women_innovators_and_inventors_by_country)
