What Phoenix, Arizona looked like in the early 20th Century

At the turn of the 20th century, Phoenix, Arizona was a city of just 5,554 people. The streets were lined with adobe buildings, saloons, and the earliest automobiles. The city had 28 saloons and 18 gambling houses, giving it the rough-edged character of a frontier town still finding its footing. But Phoenix was changing fast. Public buildings were going up, institutions were being founded, and the surrounding desert was being tamed by engineering on a massive scale.

Adobe was the defining material of early Phoenix. Mud bricks were mixed locally, dried in the open air, and used to construct nearly everything — homes, storefronts, and even the city’s first schoolhouse. As wood and brick structures began appearing in the 1890s and early 1900s, the old adobe buildings didn’t vanish immediately. They stood alongside the newer buildings, a physical reminder of how recently Phoenix had been a desert village.

On February 25, 1901, Governor Murphy dedicated the permanent state Capitol building, a milestone that signaled Phoenix’s growing status as a serious political center. An 11-acre site on the west end of Washington Street had been purchased for $130,000 to accommodate it. That same year, the state legislature passed a bill allowing cities to levy taxes to support free libraries, and the Phoenix City Council moved quickly, levying a $5,000,000 tax. Andrew Carnegie agreed to donate a library building, but set specific conditions the city had to meet first. The Carnegie Free Library opened in 1908, dedicated by Benjamin Fowler.

Washington Street was the beating heart of the city in the early 1900s. Trolleys ran along its length, businesses lined its sidewalks, and it connected the main civic and commercial institutions of Phoenix. Moses Sherman’s trolley system made it possible for residents to move across the growing city with ease, and by 1907, Washington Street projected the image of a progressive Southwestern city on the rise.

Water was everything in the desert. Without a reliable supply, Phoenix could not grow. Flooding was another danger — major floods struck in 1890 and 1891, and again in 1905, threatening the farmland and settlements that had formed along the Salt River. The construction of a canal system was an essential response. The Arizona Canal, the northernmost of the Valley’s major canals, began construction in 1895 and required regular scraping and maintenance to stay functional.

In 1903, local residents organized the Salt River Valley Water Users’ Association to manage both water and power supply for the region. That organization still operates today. The effort to control the Salt River gained national momentum when President Theodore Roosevelt signed the National Reclamation Act, which authorized the construction of dams on western streams for reclamation purposes. Construction on the Theodore Roosevelt Dam began in 1906. Before it was finished, the Granite Reef Diversion Dam opened in 1908, establishing the headgates that most Valley canals now rely on.

When the Roosevelt Dam was completed, it became the first dam built under the National Reclamation Act to supply both water and electricity. Former President Theodore Roosevelt returned to Arizona to personally dedicate the dam on May 18, 1911. The project created several freshwater lakes in the surrounding mountain ranges and fundamentally reshaped the agricultural potential of the Salt River Valley.

Phoenix’s warm, dry climate drew tuberculosis patients from across the country. At the time, the only treatment available was rest in a dry, warm environment. In 1895, the Sisters of Mercy opened St. Joseph’s Hospital with 24 private rooms specifically for tuberculosis patients. The city’s Protestant community funded the hospital despite the Catholic population being relatively small and limited in resources. The Sisters of Mercy then opened Arizona’s first nursing school in 1910. St. Joseph’s Hospital is still operating today, managed by Dignity Health, with the Sisters of Mercy remaining involved.

Religious institutions shaped more than just healthcare in early Phoenix. The Sisters also ran Sacred Heart Academy until 1901. In 1917, the Sisters of the Precious Blood opened St. Mary’s Catholic High School. A decade later, in 1928, the Jesuits established Brophy College Preparatory for boys. These schools formed the backbone of Catholic education in the city for generations.

Commerce in early Phoenix ranged from small specialty shops to industrial operations. Donofrio’s confectionary on Washington Street was a popular destination, selling candy and food out of a well-appointed interior. The Pratt-Gilbert hardware store featured a full buggy showroom. The Holsum Bakery, with roots going back to the 1880s under founder Ed Eisele, supplied bread to the city. Valley Machine Co. on West Jackson Street opened in 1909 and became the oldest machine shop in Phoenix.

Ranch life remained central to the Phoenix area well into the early 20th century. Cowboys and ranchers worked land just outside the city limits, and families like the Ryders and Pendergasts posed for photographs in front of their rural homesteads. The contrast between the growing urban core and the surrounding cattle country was a defining feature of the region in these years.

The Phoenix Fire Department in 1908 still relied on horse-drawn wagons to respond to emergencies. That same year, the Adams Hotel fire drew attention to the risks facing the city’s growing number of large commercial buildings. Emergency services were evolving, but the tools of the era were still largely those of the 19th century.

By the 1910s, Phoenix was firmly engaged in World War I. In 1917, a WWI parade moved through the streets, including a float from the Arizona Printers Union. The following year, a medal presentation ceremony for Frank Luke Jr. was held at the State Capitol. An open-air lunch on Adams Street in 1918 was organized to raise relief funds for war-torn Europe. Hailstorms also struck the city in 1917, blanketing E. Adams Street and its shops in a layer of ice.

Entertainment options expanded throughout the decade. The Lamara Theatre and the Columbia Theatre both operated in 1917, offering evening entertainment to Phoenix residents. The Apache Trail Auto Stage Company catered to tourists looking to explore the surrounding desert and mountain scenery. The Midwinter Carnival brought parades through downtown, with local figures like Will and James McCulloch riding on flatbed trucks.

Agriculture remained a major part of the economy. Dates were grown and dried locally, as seen in a 1915 photograph of Beatrice and Margaret McCulloch working with the harvest. The Arizona Citrus Growers operated a field box dump station near downtown in the 1930s. Irrigation was central to all of it — by 1937, fields stretching 70 miles from Phoenix were being actively watered through the Valley’s expanding canal network.

Tovrea Castle, an unusual multi-tiered structure, became one of Phoenix’s more distinctive landmarks. Built in the 1900s, its grounds were photographed from multiple angles, showing the striking architecture set against the desert landscape. Meanwhile, the McCulloch Brothers photography studio, located at 18 N. 2nd Avenue, documented much of the city’s daily life during this period.

The late 1920s brought significant construction to Phoenix. The Westward Ho hotel opened in downtown Phoenix, with plasterers working on its exterior in 1927 before its completion. The Arizona Biltmore opened on February 23, 1929, marking a new era in luxury hospitality for the city. That same year, Mayor Louis P. Whitney and the City Commission rode Phoenix streetcar No. 100 on its inaugural run on Christmas Day, 1928.

Education grew alongside the city. Phoenix Union High School was a central institution for students in the area, with its auditorium and science building attracting attention into the 1940s. The Phoenix Junior College also served the community during this period. The laying of the cornerstone at Monroe School in 1914 drew spectators, showing how seriously the city took its public school development.

By the 1930s, Phoenix was navigating the hardships of the Great Depression. Drought refugees arrived in August 1936, drifting through the city in search of work picking cotton. The Farm Security Administration stepped in, establishing Camelback Farms as part of a federal rehabilitation project and setting up a Rural Rehabilitation Office in Phoenix by April 1940. A sign hanging in that office reflected the federal government’s active role in stabilizing struggling families across the Southwest.

By May 1940, Phoenix had grown into a recognizable small city with paved streets, palm-lined residential blocks, a municipal golf course, and a busy downtown. A welcome sign greeted visitors entering the city. High school students gathered outside the science building. Bicycles were stacked outside Phoenix Union High School. On Saturday afternoons, an orchestra played outside a local grocery store while shoppers listened in the afternoon sun.

Tourist courts became a fixture of Phoenix by the late 1930s and early 1940s. Trailers, cabins, and motel-style accommodations attracted winter visitors drawn by the warm climate. Neon signs lit up the night at tourist courts by February 1942, and Phoenix was firmly establishing itself as a winter resort destination. The Clover Court motel, owned by Al and Kitty Mortenson, operated at 911 S. 17th Ave. in 1939 as part of this growing tourism economy.

Cooperative stores served the everyday needs of Phoenix residents in 1940. These community-focused operations stocked goods on open shelves and served customers in storefronts with clear, practical layouts. An aerial shot taken that same year shows a downtown Phoenix already dense with buildings, roads, and city blocks stretching to the northeast — a far cry from the adobe village it had been just decades earlier.

Industry ran alongside commerce throughout the early decades. The Diesel Plant powered parts of the city. The Lee Redman Co. and Dwight B. Heard Investments office anchored the commercial district. The Valley Machine Works at 701 W. Jackson Street, founded in 1909 by C.F. Johnsen, became the longest-running machine shop in the city. A meatpacking plant operated near downtown by April 1940, and workers used electric welders to repair farm trucks, showing how mechanization was transforming daily labor in the Valley.

The natural landscape surrounding Phoenix was as striking as the city itself. Piestewa Peak rose from the desert north of the city. The rim of the Superstition Mountains stretched across the horizon to the east. The Heard Pueblo, documented in multiple photographs from the 1900s, preserved a record of the ancient cultures that had lived in the Valley long before the city’s founding. The Tonto Natural Bridge, photographed in 1914, drew visitors like Dave and Lillias Goodfellow to the rugged terrain beyond the city’s edge.

From the 1900s onward, street life in Phoenix told the story of a city growing into itself. Polk Street featured a dance hall that burned in the early 1920s. Residential streets near the Hattie Mosher House showed tree-lined sidewalks and modest homes. Tents near the railroad tracks housed workers and migrants. A man hauled water to his home by hand as late as 1940, a reminder that not all residents had equal access to the city’s expanding infrastructure.
