National Scientist Gregorio Y. Zara "Renowed Engineer and Inventor"

National Scientist Alfredo C. Santos "Father of Natural Products Research"

Dr. Alfreo C. Santos worked on the chemical components of local herbal plants for their medicinal properties.

He isolated and characterized these chemicals called alkaloids which has healing effects. For his worked on alkaloids plants, he was conferred as National Scientist in 1978 by the Philippine President.

He was born in Sto. Tomas, Pampanga on August 15, 1900. He finished his Bachelor of Science and Master of Science in Pharmaceutical Chemistry in the University of the Philippines. He graduated his doctorate degree in Pharmacy in the University of Santo Tomas.

He studied the chemistry of medicinal plants in the philippines particularly alkaloids. Alkalois is one of the most poisonous medicines. One of his studies is the alkaloid from kalimatas, a small tree native to Philippine Forest. In folk medicine, the water in the bark of kalamitas is treatment for sore eyes and this alkaloid  called phaeanthine. In 1931, he won the Anacleto del Rosario gold medal.

Furthermore, the phaeanthine shown to include lowering of blood pressure and mosquito control as well as it was also found other activities such as anti tubercular and anti inflammatory. Dr. Santos also isolated alkaloids from the other plants such as susong kalabaw and anonas. He believes that anonas fruit can stop diarrhea and dysentry.

In 1952, he was awarded  as "Outstanding Pharmacist Researcher" by Philippine Pharmaceutical Association.In 1957 from the UP Alumni Association awards him the "Distinguished Alumni Award". In 1974, the Philippine Assocoation for the Advancement of Science granted him the "Most Outstanding Scientist Award. In 1954, President Ramon Magsaysay awards the Service Medal and Diploma of Merit. In 1978, Dr. Santos was selected as the first members of the National Academy of Science and Technology. In July 10, 1978, he was conferred the rank o the National Scientist by the President Ferdinand E. Marcos for his significant contributions in phytochemistry.

He passed away in year of 1990.

YoYo "Not Filipino Invention"

Pedro Flores

Yoyos date as far as back 500 B.C and at that time it could only played up and down to the string. But the Filipinos played it differently on the way how they tied the yoyo. In 1920, Pedro flores introduced to the world the different method of stringing the yoyo, which it is possible to do other tricks. 

He was born in Vintar, Ilocos Norte, Philippines and go to the United States in 1915. Between 1919 and 1920 he attended the High School of Commerce in San Francisco 1919-1920 and subsequently studied law at University of California, Berkeley and the Hastings College of Law in San Francisco. Flores dropped out of school and moved to Santa Barbara, California and he worked as a bellboy,

Between 1928 and 1932, Flores started and ran the Yo-yo Manufacturing Company in Santa Barbara before selling the company and trademark to Duncan who continued to market and sell Flores yo-yos alongside the Duncan line.

Furthermore, He registered this innovation under the trademark Flores YoYo. This is the reason why "yoyo" was considered a tagalog word and the Philippines has the distinction of officially naming the toy and perfecting of using it.

Many inventors tried to improve the yoyo but none came out and still better the original from the Philippines.

Lunar Roving Vehicle "Filipino made"

Moon Buggy also known as Land Rover

Eduardo San Juan, is a graduate of Mapua Institute of Technology (MIT). He worked for Lockheed Corporation and conceptualized the design of the Moon Buggy of the Apollo astronauts used while in the moon. He is a NASA Engineer and San Juan reportedly used his Filipino ingenuity to build a vehicle that would run outside the Earth's atmosphere. He constructed his model using homemade materials. In 1978, San Juan received one of the Ten Outstanding Men (TOM) awards in science and technology.

Philippines postage stamp commemoration

The Filipinos consider Eduardo San Juan as the inventor of the Moon Buggy or more popularly known as the Lunar Rover. The Moon Buggy was the car used by Neil Armstrong and other astronauts when they first explored the moon in 1969.

However, he was not listed as the inventor of the Moon Buggy in American scientific journals. It said the vehicle was designed and constructed by a group of space engineers. In Poland, the Moon Buggy is attributed to a Polish inventor. Worse, the National Academy of Science and Technology (NAST) does not recognize her in its roster of outstanding Filipino scientists.
