On any given day in Houston, humidity is the sole owner of the real estate above the brow. It’s so hot, in fact, that a short walk can result in a slow drip south of the jawline. Luckily for Mark Young, Ph.D., he has access to one of the coolest spots on the University of Houston campus. 

A historian and archivist at the Conrad N. Hilton College of Global Hospitality Leadership, Young looks after the school’s vast Hospitality Industry Archives. The collections constitute one of the world’s premier repositories of hospitality history, which draws researchers, industry leaders and international media. 

Within its walls, shelves are brimming with boxed and stacked materials, old hotel magazines and vintage menus, prewar packaging and photographs, film memorabilia, and stationery from decades past. For preservation reasons, the room’s temperature is kept extra cold, its humidity super low. 

“If I have a meeting across campus, the first thing I do is hang out in the archive for about five minutes to cool down,” Young says, smiling. 

Cool in every sense of the word, the archives are not just a spot to harbor relics of an ever-evolving industry. It’s here that the hospitality industry keeps its receipts, compiling a living, breathing testament to history set against the quiet hum of preservation. 

Conrad Hilton: The Myth vs. The Man

Young dedicates much of his time to studying and sharing the Conrad Hilton collection; it is, after all, the largest in the archives. But any notions that the hotel magnate always lived a charmed life are dispelled once Young describes Hilton’s childhood. 

Born in territorial New Mexico, the man who would become synonymous with global hospitality was raised in a little town that barely registers on today’s maps. Young has pictures of the house Hilton grew up in: With sun-dried bricks made of earth, water and straw, it’s a far cry from the modern designs that would eventually bear his name. 

“He came from very humble beginnings but chose a very successful path forward,” Young says. “He chose hotels out of dumb luck. A fun piece of trivia: The first hotel bearing his name is still in existence in downtown Dallas. It’s not a Hilton anymore; it’s a Hotel Indigo. But it’s still standing.” 

According to Young, many hospitality giants come from modest origins. Take Norman Brinker, who started his restaurant empire with a single Steak & Ale in Dallas, or Bill Marriott, whose parents founded a nine-stool A&W Root Beer stand in Washington, D.C., then expanded it into the Hot Shoppes franchise. The best part, Young says, is that they were all eager to pay their success forward. 

The Coolest Revolution

One of the lesser-known turning points revealed by the archives is the 1950s air-conditioning revolution. Young says an advertisement revealed to him the impact of air-conditioning not just on hospitality but on the urban economy as a whole. 

Holding up an original advertisement from the ’50s, Young points out the man wearing a suit as he sits on the chair inside his hotel room and reads the paper. Meanwhile, a woman believed to be his wife stands near him, dressed in heels and pearls. 

“I love that the woman is wearing her pearls. That’s, of course, the only way my wife and I travel,” Young says, jokingly. 

Printed atop the page, a statement reads, “Hilton Hotels lead the way in air-conditioning.” 

It was customary for Hilton’s hotels in the South to have AC; however, his properties in Chicago, New York and elsewhere went without, leading to staff layoffs during the sweltering summer months. Taking out a loan to equip every one of his hotels in the northern states with AC, Hilton, in turn, not only kept his guests comfortable but also enabled the hotels to keep their employees staffed throughout the year. 

“Once they air-conditioned the buildings, it created a 12-month convention business and transformed hospitality into infrastructure,” Young says. “That loan was paid off in a few short years.” 

Of course, climate control wasn’t the only way the industry quietly redefined modern life. As hotels reengineered buildings, they were also recalibrating culture. 

Hospitality often responded to social change before it was fully normalized. A perfect testament to that is Marie Dobson. Just 19 years old when she started her career in hotels, Dobson would retire as president of Hilton Reservations in the 1990s, shattering the glass ceiling on her way out. 

“She saved everything,” Young says of Dobson’s meticulous records — a paper trail tracing the evolution of reservations from telegrams to telegraphs to telephones to, eventually, computers. 

Her career unfolded alongside another shift happening in plain sight. As more women were traveling solo for work or simply for independence, Hilton met the moment with his 1950s Lady Hilton concept. Outfitting his hotels with female-only floors, ironing boards as built-in amenities and perfume bottles stamped with the Hilton logo, he was engineering the glam room before the glam squad became a thing. 

The Hollywood Factor

From lived history to performed history, the hospitality archives not only reflect society but also shape how society sees and remembers itself. Aiding production teams for such iconic television shows as Matthew Weiner’s “Mad Men” and historical big-screen features like Steven Spielberg’s “Bridge of Spies,” Young has helped Hollywood get the details right — down to how hotel linens were folded. 

“For ‘Mad Men,’ they wanted to know about Hilton’s hotels in 1963,” Young says. “That was such a pivotal year. Conrad was on the cover of Time magazine; he’d just opened 13 hotels around the world.” 

There was one aspect of the show, however, that producers got wrong, according to Young. He says it was a decision made without his guidance. 

“I remember watching, and the actor they got to play Conrad [Chelcie Ross] was pretty good, but the moon stuff was not. Building the Lunar Hilton was an idea of Barron Hilton’s, Conrad’s son, who was an aviator,” Young says. 

As for Spielberg’s team, they get high marks from Young. “They even folded the napkins on the tables of the Berlin Hilton restaurant perfectly,” he says. “They really did a good job, and it’s the little details that matter.” 

Honoring Evolution

One of the newer additions to the Hospitality Industry Archives is The Hall of Honor, a pseudo-museum located on the lower floor off the lobby entrance that invites visitors to explore the evolution of the industry through restaurant, hotel and other hospitality memorabilia. Amid the host of artifacts is a Howard Johnson waitress uniform — its aquamarine-and-ivory houndstooth standing out in a sea of archives. 

“That uniform was released in the mid-’60s,” Young says. “Howard Johnson was trying to update their image, and the person they recruited to design it was Christian Dior.” 

Though it might be a small detail — a pattern, a hemline, a name stitched into fashion history — it tells a much larger story. 

“These archives really do show a reflection of our society as we have evolved,” Young says. 

From shifting gender roles to globalization, from the convention economy to design evolution, hospitality is service. It’s culture. It’s life. Hospitality is how we relax, gather, negotiate, celebrate and even grieve. It’s luxury, but more than that, it’s simplicity. 

“Despite all the bells and whistles, a nice clean room, a nice pillow — those simple things still matter,” Young says. 

So, next time the Houston sun is bending your will to live, make an appointment to visit the Hospitality Industry Archives with Young. Take in the cold air, luxuriate in the quiet corners, hold the empty soap wrappers. And think about the flight attendant who traveled alone, the convention in July made possible because of air-conditioning and the history folded into the dinner napkins featured for no more than 30 seconds in Spielberg’s war-torn thriller. You’ll be better for it.
