#1 – The Birthplace of California

Guess where Europeans first arrived when they hit the beautiful state of California? Oh, that’s right San Diego! San Diego is often referred to as the birthplace of California as it’s where Europeans first landed and settled.

#2 – Who Got Here First?

There was an Iberian explorer, Juan Rodríguez Cabrillo, who claims to have discovered San Diego Bay in 1542, on behalf of the Spanish Empire. That would mean that he found San Diego first, approximately 200 years before Europeans actually settled the area. Well, if we go way back, Native Americans have been living in the area for around 12,000 years before the Europeans even showed up. So take that!

#3 – Over The Years 

The first fort and mission was founded in San Diego in 1769 under Spanish Rule, and then later it went under Mexican rule starting in 1821. However, it wasn’t until 1848 that San Diego officially became a part of the USA. Well, we’re glad that’s official.

#4 – San Diego: A Small City

According to a census in 1850, the population of San Diego was only 650 people. And ten years later, in 1860, the population had only slightly risen to 731 people. However, 10,000 men stopped on by San Diego while on their way up to Northern California to try their luck in the gold mines. Unfortunately, they were only passing visitors, as San Diego just didn’t get a lot of people sticking around back in the 1850s and 60s.

#5 – Population on the Rise

The population of San Diego apparently grew in fits and bursts. Periods of population booms were in the 1880s and from 1900 to 1930. It’s crowning gem of a population number back then was a whopping 148,000 people in 1930. From then on, the Numbers just got bigger and bigger each year. Today, the population sits at nearly 1.34 million.

#7 – San Diego: Tuna Capital of the World

Well, this might not be true these days, but from the 1910s to the 1970s San Diego was deemed the “Tuna Capital of the World!” The American tuna fishing fleet and the tuna canning industry were both based out of San Diego. 

#8 – Who Runs The Tuna Business?

Well, let’s just say that back in the beginning of the tuna industry in San Diego, it sure wasn’t the natives who were running the show. Immigrant fishermen were really the stars of the tuna business, with the largest population of foreign-born fishermen being from Portugal in the beginning of the 20th century. However, it was the Japanese owners and fishermen who were responsible for catching 80% of all the tuna in the area!

#9 – The Yippie Fleet AKA The Pork Chop Express 

During WWII, fishing wasn’t feasible. However, there were 53 tuna boats who served the US Navy as the “Yippie Fleet.” They also went by another name, the “Pork Chop Express” as they were known for food delivery. Now we have UberEats and GrabFood, but back in the day, the troops just had the Pork Chop Express… but in all seriousness, the Yippie fleet lost a lot of ships, and lots of crew members were lost as well. They were awarded more than a dozen battle stars due to their bravery and service.

#10 – When The Great Depression Isn’t So Bad

For San Diego, the Great Depression actually wasn’t as bad as it was for the rest of the state, let alone the country. The population actually got bigger rather than smaller, and there was still enough money to build some new municipal structures. You probably are thinking about buildings like a firehouse, but no, San Diego built a new golf course and tennis courts too. San Diego sure wasn’t scrimping.

#11 – Why Was There So Much Money?

Well, in 1935 the US wanted to show to Japan the value they place on the Pacific Ocean, and they also wanted to demonstrate their military power. Therefore, the entire Pacific Fleet assembled in San Diego. And then the Consolidated Aircraft Corporation located in New York, moved all 800 employees to San Diego to open an assembly plant.

Essentially, during the Great Depression, the USA still wanted to seem strong and powerful, and San Diego was one of the places they decided to put their feet down and stand strong. This, of course, boosted San Diego’s population and economy.

#12 – Say Hello To Kate Session’s Vision

Balboa Park started as 1400 acres of land that the San Diego government decided to dedicate to a park back in 1868. It actually sat undeveloped for over 20 years and was just called “City Park.” However, in 1892, one woman had a vision for the park: Kate Sessions. As a savvy business woman and botanist, she offered to plant 100 trees a year in the Park in exchange for 32 acres for her own plant business. San Diego said yes, and to this day Kat Sessions is referred to as “The Mother of Balboa Park.” 

#13 – Wait, Balboa Park is Bigger Than Central Park?

#15 – How Is A Zoo Born?

The San Diego Zoo actually started when there were exotic animals abandoned after the 1915 Panama-California Exposition. No one was quite sure what to do with these wonderful creatures, so Dr. Harry M. Wegeforth thought, “Let’s Have A Zoo!” And thus, he established the Zoological Society right here in San Diego. Today the zoo has 3,700 animals and sits on over 100 acres.

#16 – What’s In A Frozen Zoo? Penguins?

The San Diego Zoo actually has a very special department, that is called the Frozen Zoo. This actually isn’t where the penguins and polar bears live, and it’s not even a touristy place to go, it’s a scientific lab and library that is tasked with collecting and containing frozen specimens of DNA of the animals. Specially, they are doing research on breeding endangered species.

One of the most famous animals of all, that has ever graced the grounds of the San Diego Zoo, was an orangutan for Borneo. His name was Ken Allen and he lived from 1971 to 2000.
