The Stewarts at Westwood

Robert Bruce Stewart (HDR M’68), known as R.B., joined the Purdue University staff as controller in 1925. At that time, Purdue enrolled 3,000 students, the physical plant was worth $3 million, and the endowment totaled $340,000.

Stewart, who went on to become the university’s first vice president and treasurer, is credited by many with influencing the character and growth of Purdue University. He spent 36 years building the university both fiscally and physically.

Geochemist Marissa Tremblay ’12 analyzes Antarctic rocks to unravel Earth’s climate chronology and predict the planet’s future environment

A geologic field excursion to Death Valley during spring break her first year at Barnard set Marissa Tremblay ’12 on course to becoming a scientist. She entered college intending to pursue a law degree, but stepping foot on that vast, desolate desert landscape marked with sand dunes ignited a curiosity to uncover the stories in stones.

50 Years of Wolf Park

Founded by Purdue ethologist Erich Klinghammer in 1972, Wolf Park began as an experiment to study wolf behavior. The pioneering research conducted there over the past 50 years contributed to a better understanding of the apex predator and facilitated its reintroduction into the wild.

Twenty Years After 9/11 Longhorn Reflects on the Unexpected Detour—and the Subsequent Broadway Show—that Altered His Life’s Trajectory

On the morning of September 11, 2001, Kevin Tuerff and his then-partner, also named Kevin, were on an Air France flight bound for New York City. The couple had just wrapped up a European vacation and they were eager to get home. A sudden drop in elevation over the Atlantic Ocean was the first sign that something was amiss. Then came an announcement from the cockpit.

Pioneering journalist Betsy Wade ’51 broke barriers for women in news

When Betsy Wade ’51 became the first woman to edit the news in the 105-year history of The New York Times, she noted the spittoons vanished from the city room within her first week. Her landmark appointment to the copy desk in 1956 signaled a new era for women in journalism, previously relegated to women’s pages that covered the “Four F’s” — family, food, furnishings, and fashion.

Donation of House Honors Al Altschaeffl, who Contributed to Many Iconic Campus Structures

What do Mackey Arena, Neil Armstrong Hall of Engineering, the Bell Tower and the Gateway to the Future arch have in common? They are among the more than 170 building projects across campus with soil foundations designed by Al Altschaeffl (BSCE 1952, MSCE 1955 PhD 1960), a professor of civil engineer-ing with expertise in geotechnical engineering who continued to consult on projects following his retirement from the University in 2000.

New methodology may one day map forests around the world

What if we could map every tree on the planet?

It’s a question that drives the work of Joshua Carpenter (MS’20), a PhD student and researcher in the Geospatial Data Science Lab supervised by Jinha Jung, Assistant Professor of Civil Engineering.

Just as the field of precision agriculture uses high technology sensor and analysis tools to measure the growth and health of fields of crops, Carpenter is developing methodologies that could one day be similarly applied to forests around the globe.

Mopping produces pollutants similar to vehicle emissions

The fresh-scented products used to clean our homes and offices come with risks to our respira-tory health. The chemicals used to create scents such as lemon and pine pollute indoor air with nano-sized particles in similar ways that motor emissions affect the air we breathe outdoors, according to a new study published in the journal Science Advances.

Physics equations drive optimization of complex engineered systems

Computational models allow researchers to analyze and design complex systems, but development can be a slow process. Leifur Leifsson, associate professor and principal investigator of the Computational Design Lab, uses physics equations to optimize engineered systems for aircraft and space systems as well as microwave systems, nondestructive testing systems and food-water-energy systems.

Telescoping prosthesis enables 10-year-old girl to bow violin

It’s atypical to see a piano as part of a grade school orchestra ensemble, but that’s exactly what Zayra Vincent encountered when she visited the Burgin Elementary School music room this spring. There, in the back of the Arlignton, Texas, classroom, a smiling 10-year-old girl plucked out notes on the keyboard with one finger.

Innovative Boilermakers whose work impacts the daily lives of millions

From his fourth-floor home office perched on so-called Billionaires Row, Keith Krach (IE’79) can see the entirety of the San Francisco Bay and the famous Golden Gate Bridge that spans the strait connecting the bay to the Pacific Ocean. It’s an impressive vista and a far cry from his hometown of Rocky River, Ohio, a Cleveland suburb.
