Imagine a world drained of vibrancy, where sunsets are grey smudges and fields of wildflowers blur into a monotone tapestry. This was the reality of television viewers until 1940 when a young Mexican engineer named Guillermo González Camarena dared to dream in living color.

His invention was not a brush or a tube of paint but rather a revolutionary system for color television broadcasting.

At the tender age of 23, and with limited resources and boundless imagination, Guillermo crafted a “chromoscopic adapter,” a device that could transform existing black and white cameras into color capturers.

His secret weapon? A spinning disc adorned with red, green, and blue filters, dances in perfect synchrony with the television’s scanning beam.

But Camarena’s journey wasn’t paved with roses. Facing skepticism and bureaucratic hurdles, he tirelessly championed his invention.

He built his television station, XE1-GC, to showcase the magic of color broadcasting, and used it to pioneer educational programming and medical telecasts.

His dedication paid off. In 1946, he beamed the first-ever color television transmission, forever etching his name in the annals of technological history.

He died in a car crash in Puebla on April 18, 1965, at the age of 48, while returning from examining a television transmitter at Las Lajas, Veracruz.

2. Miguel Ondetti (Argentina)

Argentine-born American chemist, Miguel Ondetti (May 14, 1930 – August 23, 2004) invented captopril, the first ACE inhibitor that was used to treat high blood pressure, heart failure, and diabetic kidney disease

Ondetti was born and raised in Buenos Aires and earned his PhD in chemistry from the University of Buenos Aires in 1957. In 1960 he moved to The Squibb Institute for Medical Research in New Jersey. It was here that he encountered a formidable foe – angiotensin-converting enzyme (ACE), a protein that constricts blood vessels, sending blood pressure soaring.

For years, scientists had grappled with ACE, its invisible grip causing heart attacks, strokes, and a symphony of silent suffering. Ondetti, however, saw not an insurmountable obstacle, but a puzzle begging to be solved.

With a tenacity fueled by compassion, he embarked on a molecular odyssey. He scoured the natural world, seeking a molecule that could bind to ACE, silencing its constricting song. He settled on using a sulfhydryl group which binds strongly to zinc.

Finally, after years of tireless work, a breakthrough. He synthesized a tiny molecule, captopril, that fit snugly into ACE’s active site like a key unlocking a door. It lowered blood pressure, reduced heart attacks, and improved the lives of millions.

3. Julio Palmaz (Argentina)

Before 1986, blocked arteries-coronary artery disease-, like a choked highway, threatened to cut off vital blood flow to the heart, leading to strokes, heart attacks, and a sudden end to the journey of life.

An Argentine-born inventor named Julio Palmaz intervened, armed not with scalpels and lasers, but with a revolutionary tool – the first balloon-expandable stent.

Julio Palmaz was born on 13 December 1945 in La Plata, Argentina.  He is a vascular radiology doctor who works at the University of Texas Health Science Centre in San Antonio.

Julio studied medicine at Argentina’s National University of La Plata, graduating in 1971. He then worked in vascular radiology at the San Martin University Hospital in La Plata before transferring to the University of Texas Health and Science Centre in San Antonio.

Julio invented the balloon-expandable stent, a tiny mesh tube, folded like a deflated balloon, that could be inserted into a clogged artery and then expanded, pushing the blockage aside and restoring vital blood flow. Finally, in 1986, his dedication paid off. The first successful implantation of his stent marked a watershed moment in medical history.
