Cal Poly: Brand overview
Cal Poly’s history began with Myron Angel, a journalist and local historian who campaigned from 1894 for a public polytechnic school in San Luis Obispo, California. His efforts led to the signing of the law on March 8, 1901, by Governor Henry T. Gage, establishing the California Polytechnic School. The school opened on October 1, 1903, with 20 students and a three-year program in crafts, agriculture, and domestic science.
Enrollment grew slowly, but World War I reduced student numbers and funding between 1917 and 1919. In 1921, control moved to the California State Board of Education. By 1927, the name “Cal Poly” was already in common use. In 1930, women were barred from admission by state law, ending the school’s early coeducational model for nearly three decades.
The Great Depression nearly closed the campus, and California officials even discussed turning it into a state prison. In 1933, Julian McPhee became director and shifted Cal Poly toward stronger agricultural programs. The same year, he formalized the “Learn by Doing” principle. In 1938, the Voorhis family donated a Southern California ranch for horticultural training. In 1940, Cal Poly became a college, and in 1942, it awarded its first higher education degrees.
After World War II, veterans arrived under the GI Bill, and the campus built “Vetville” housing for married students. Engineering programs resumed in 1946, and women returned in 1956-1957. Cal Poly joined the California state college system in 1960, became a university in 1971, and grew from 6,000 students in 1960 to 16,000 by 1980. In 2001, its centennial fundraising campaign raised more than $264 million.

before 2019
The Cal Poly logo combines a classic crest with a text component. The shield is divided into four sections, each containing a symbol representing different fields of education.
A binary code in the upper left section symbolizes technology and computer science. To its right, an atom represents natural sciences and engineering. The lower part of the shield features a sheaf of wheat, symbolizing agriculture, and a hammer with a quill, referring to labor and knowledge.
A ribbon runs across the center of the crest, displaying the Latin motto “Discere Faciendo,” which translates to “Learn by Doing.”
Next to the shield, the text “Cal Poly” is displayed in a serif font, giving the logo an academic and authoritative appearance. The color scheme is rendered in dark green tones, reflecting the university’s connection to nature and its agricultural roots.
2019 – today
The new university’s logo is a heraldic shield bearing the phrase “Cal Poly” behind it.
The shield is visually divided into three parts.
- At the top of the dark bar is the university’s motto: “Learn by doing” (learn by doing). Cal Poly emphasizes hands-on learning. Students apply the knowledge they have acquired in practice. The university has its own ranch where research and experiments take place. Laboratories are also located on the upper floors of the new six-story science building. Each student must complete a practical project upon graduation to apply the knowledge gained.
- The sun rises from behind the mountains at the second level of the shield. This is reminiscent of the mountains and the sun of California, where the university is located. In a figurative sense, the sun of science, personifying the university, rises and illuminates the earth, spreading knowledge.
- The last part of the shield is the largest. It is a white space with a crossed feather and hammer in the middle. The picture unites knowledge and work. It shows that knowledge cannot be translated into action; otherwise, learning is a waste of time. The image completely echoes the motto. The programs are also built on the combination of technical knowledge and art.
The inscription “Cal Poly” is located approximately in the middle of the shield. This is an abbreviation of the full name Cal (California Polytechnic).
The Seal
The seal of California Polytechnic State University is designed in a classic university style, based on the heraldic shield symbolism used until 2019. Surrounding the crest is a circular band featuring the university’s full name, presented in a traditional serif font. The year of establishment, 1901, is displayed at the bottom of the circle.
The university seal highlights the combination of science, engineering, agricultural knowledge, and the humanities, reflecting the institution’s multidisciplinary nature.
