Dr. Charles R. Drew: The Father of the Blood Bank
In the 1930s and 40s, one man’s groundbreaking medical research transformed how we save lives — and his legacy still flows through hospitals around the world.
Dr. Charles R. Drew (1904–1950), an African American physician and surgeon, discovered a better way to store and transport blood plasma. Plasma, the liquid component of blood, can be preserved longer than whole blood and safely shipped over great distances — a game changer for emergency medicine.
@stmblog He revolutionized how we store blood, saved thousands in WWII, and stood up to injustice. 🩸 Meet Dr. Charles R. Drew — the Father of the Blood Bank.

During World War II, Drew’s expertise powered the “Blood for Britain” program, which sent vital plasma to soldiers and civilians injured in the Blitz. Later, as the first director of the American Red Cross blood bank, he helped establish modern blood collection and distribution systems.
But Drew was more than a scientist — he was a man of principle. He resigned from the Red Cross in protest over its policy of segregating blood by race, a practice he condemned as scientifically baseless and morally wrong.
Known today as the “Father of the Blood Bank,” Dr. Drew’s innovations continue to save millions of lives every year. His story is a testament to the power of science, dedication, and courage to challenge injustice.

LOS ANGELES — Century Boulevard is one of the most recognizable east–west corridors in South Los Angeles, stretching from Watts to Los Angeles International Airport (LAX). But despite its grand-sounding name, the origin of “Century” is surprisingly simple—and rooted in math.
The Meaning Behind “Century”
Century Boulevard sits roughly 100 blocks south of downtown Los Angeles, where the city’s street numbering system begins at 1st Street and Main Street. Instead of naming the road “100th Street,” city planners opted for a more distinctive and memorable name: Century Boulevard.
In this case, “Century” literally means 100.
Part of Los Angeles’ Grid System
Los Angeles was designed using a grid-based street layout, especially in its expanding southern neighborhoods during the early 20th century. Streets were often named or numbered based on their distance from downtown.
Century Boulevard aligns with what would have been the 100th Street corridor—making it a key reference point in the city’s geography.
A Street That Evolved Over Time
Before it became Century Boulevard, portions of the roadway were known by other names, including Pine Avenue and San Antonio Street. As the region developed and expanded, these segments were unified under a single name in the 1920s.
This consolidation helped streamline navigation and supported growing transportation needs.
From Local Road to Global Gateway
The importance of Century Boulevard grew significantly with the rise of Los Angeles International Airport (LAX). Today, it serves as a major gateway for millions of travelers entering the city.
The road connects diverse communities—from historic neighborhoods in South Los Angeles to the bustling airport corridor—making it both a local lifeline and an international entry point.
More Than Just a Name
Century Boulevard reflects a broader pattern in Los Angeles street naming:
- Some streets honor historical figures
- Others reflect geography or culture
- And some, like Century, are rooted in the city’s structured grid system
It’s a reminder that even the most ordinary street names can reveal deeper stories about how a city was built.
The Bottom Line
Century Boulevard isn’t named after an event—it’s named for its location. Positioned at the 100th Street line, it represents both the logic of Los Angeles’ design and the growth of the city over time.

Forgotten Genius Friday: The Gas Mask and the Man Who Invented It
Garrett Morgan, the inventor behind the modern gas mask and traffic signal, risked his life in 1916 to save workers trapped in a tunnel explosion beneath Cleveland. Though his invention worked and lives were saved, the media largely erased his name because he was Black. This is the story of a hero history tried to forget.

🎥 The Knowledge – Episode: Garrett Morgan
“The man who gave us stoplights also saved lives underground.”
Before Garrett Morgan became known for inventing the three-position traffic signal, he was already changing the world—one breath at a time.
In 1912, Morgan designed a safety hood to protect firefighters and miners from the deadly smoke and toxic fumes they faced on the job. This early version of the gas mask featured breathing tubes and a wet sponge to filter air—simple, yet revolutionary.
But the true test came in 1916, when a natural gas explosion rocked a tunnel under Lake Erie in Cleveland. With little hesitation, Morgan donned his invention and entered the chaos. He saved multiple workers trapped beneath the earth—risking his own life to prove his device could do what others hadn’t even imagined.
Despite his heroism, headlines of the day often left out his name. Why? Because Garrett Morgan was Black. His contributions were buried in the shadows of racial prejudice, even as his inventions were saving lives and modernizing cities.
Today, we’re changing that narrative.
Garrett Morgan didn’t just invent the gas mask—he proved it worked. And his legacy deserves to breathe.

Why Phoenix’s Skyline Has Stayed Low — And How It Compares to Los Angeles
Discover why Phoenix’s skyline lacks supertall skyscrapers, from FAA flight path limits near Phoenix Sky Harbor International Airport to how it compares with Los Angeles’s skyline growth.
Last Updated on March 25, 2026 by Daily News Staff
Phoenix is the fifth-largest city in the United States, yet its skyline doesn’t resemble other major metros like Los Angeles, Chicago, or Dallas. Despite rapid population and economic growth, downtown Phoenix has long lacked supertall skyscrapers — and until recently, didn’t even have a building tall enough to qualify as a true “skyscraper” under standard definitions.
The Basics: Phoenix’s Height Reality
The tallest structure in Phoenix for decades has been Chase Tower, rising to about 483 feet. Under the Council on Tall Buildings and Urban Habitat definition, a skyscraper reaches at least 492 feet — which means Phoenix has technically lacked one — despite its size and population.
A new project, the Astra Tower, is planned to rise around 540+ feet when it breaks ground, potentially giving Phoenix its first true skyscraper.
Airport Proximity: The FAA’s Height Grid
FAA Obstacle Evaluation & Downtown Limits
Phoenix’s skyline constraints are rooted in aviation safety.
📍 Phoenix Sky Harbor International Airport sits just a few miles from downtown.
- The Federal Aviation Administration (FAA) regulates building heights near airports so they don’t obstruct flight paths, require planes to alter approaches, or interfere with climb-out safety.
- In Phoenix, this results in a layered set of height limits that vary by location and elevation above sea level — often measured in feet above mean sea level (MSL) rather than simply building height from ground.
The city’s zoning code divides downtown into multiple contour zones with distinct maximum elevation values (e.g., 1,275 ft, 1,525 ft, 1,700 ft MSL), each tied to how close it sits under airport flight paths.
That means in some blocks you can’t build above a specific elevation even if ground levels are lower — a regulatory “roof” that varies across downtown.
City zoning also explicitly states that no building can exceed the FAA’s airport height limits, even if other bonuses or zoning allowances exist.
Phoenix vs. Los Angeles: A Quick Comparison
Los Angeles: Higher Limits, Different Constraints
Cities like Los Angeles also have nearby airports (e.g., Los Angeles International Airport), but their key business districts aren’t directly under major flight corridors.
LA’s downtown has:
- Taller office and residential towers
- A financial core with dense development
- Fewer FAA-driven overlays because the flight paths stretch past the downtown edge
Los Angeles’s tallest buildings — including Wilshire Grand Center (~1,100 ft) and U.S. Bank Tower (~1,018 ft) — were built where FAA restrictions don’t force low ceilings. FAA evaluations were conducted but didn’t cut as deeply into downtown zoning compared to Phoenix.
Phoenix, by contrast, sits right under approach and departure corridors — leading to consistent FAA involvement in almost every proposed mid- or high-rise downtown.
Economic and Planning Philosophies
Beyond FAA rules:
- Phoenix developed in the automobile era, with vast inexpensive land encouraging horizontal growth.
- Los Angeles grew earlier with heavier investment in centralized neighborhoods and higher density.
- Phoenix’s village plan long encouraged multiple smaller hubs instead of concentrating all growth in one downtown core.
These historical differences mean Phoenix didn’t have the same economic “pressure” to build up — even with zoning that allows significant height if FAA permits are met.
What This Means for Phoenix’s Future
Phoenix still has room to grow vertically — but:
- FAA height contours will remain the ceiling unless flight paths change
- Developers must secure determinations of no hazard from the FAA before going taller
- New projects like Astra show demand for taller buildings is rising
As Phoenix’s urban core densifies and land becomes scarcer, its skyline may yet reach higher — but always within the invisible grid drawn by aviation safety.
