## Summary

A 2023 U.S. Census Bureau historical profile of Philo Farnsworth, published as part of their monthly history series. This government source documents Farnsworth's birthplace in Beaver, Utah, the January 7, 1927 patent filing, and the September 7, 1927 demonstration of the first all-electronic television transmission.

## Useful Claims

- Philo T. Farnsworth was born in Beaver, Utah on August 19, 1906.
- Farnsworth filed his first television patent on January 7, 1927.
- On September 7, 1927, he successfully demonstrated the first all-electronic television transmission in his San Francisco laboratory.
- The Census Bureau profile positions Farnsworth as the inventor of electronic television distinct from mechanical television predecessors.

## Reliability Notes

As a U.S. federal government publication, this source has high institutional credibility. The Census Bureau history series is produced for public education and is well-suited as a secondary source for established biographical and invention facts. It is not a primary source (not a contemporaneous record) but draws on documented historical scholarship.
