Joseph Nisbet LeConte (born February 7, 1870 – died February 1, 1950) was a famous explorer, photographer, and mapmaker. He loved the Sierra Nevada mountains. He also taught mechanical engineering at a university.

Early Life and Education

Joseph Nisbet LeConte was born in Oakland, California. His parents were Joseph and Caroline LeConte. Friends called him "Little Joe." This was because he was short and his father was also named Joseph LeConte. His father was a geology professor.

Joseph often used "J. N. LeConte" for his photos and writings. He started at the University of California, Berkeley in 1887. He earned his first degree there in 1891. Later, he got a Master's degree in Mechanical Engineering. This was from Cornell University in 1892. Soon after, he became a professor at UC Berkeley. He started by teaching how machines move.

Amazing Discoveries and Teaching Career

From 1912, LeConte taught about how machines work for over 20 years. He was a professor at UC Berkeley for 45 years.

Building an X-ray Machine

In 1895, a German scientist named Wilhelm Röntgen found X-rays. News about this discovery spread quickly. LeConte read about it in a newspaper. He then found special tubes that his uncle had for the university's lab.

LeConte and his team quickly built an X-ray machine. Within a week of hearing the news, they used it. They took pictures of a bullet inside a young boy's arm. This was a very fast and important achievement!

Other Engineering Work

LeConte also studied how different materials worked in gas turbines. He built a special machine called a harmonic analyzer. This machine helped him study how electric power lines performed.

Exploring and Mapping the Sierra Nevada

LeConte loved mountain climbing since he was a teenager. He spent many weeks exploring the Sierra Nevada mountains.

Creating the First Sierra Club Map

He created the very first map of the central Sierra Nevada. He made this map for the Sierra Club. At that time, official maps from the U.S. government were not available. His map was very helpful for other explorers.

Pioneering the John Muir Trail

In 1908, LeConte went on a big adventure. He was with James S. Hutchinson and Duncan McDuffie. They explored a new high mountain path. This path went from Yosemite National Park to Kings Canyon. This route is now part of the famous John Muir Trail.

Their trip lasted 28 days. They traveled 228 miles through high mountains. They explored parts of the mountains that no one had seen before.

Photography of the Mountains

LeConte was a very skilled photographer. He took many pictures of the Sierra Nevada. This included the High Sierra and the Hetch Hetchy Valley. He took photos before the valley was flooded by a dam.

He used heavy, fragile glass plates for his photos. He had to carry them carefully through the wilderness. In 1944, the famous photographer Ansel Adams praised LeConte's work. Adams said LeConte's photos showed a deep feeling for the mountains. He called them "creative, sympathetic statements."

Leadership in the Sierra Club

LeConte was a founding member of the Sierra Club. He was a member his whole life. He held many important roles in the club.

After John Muir passed away, LeConte became the club's second president. He served from 1915 to 1917. He helped create the John Muir Trail through the High Sierra. This trail was a tribute to John Muir.

LeConte was on the Sierra Club's Board of Directors for a long time. He served from 1898 to 1940. He was also a vice president, secretary, treasurer, and helped plan outings.

In 1901, he married Helen Gompertz. They met through the Sierra Club.

Places Named After LeConte

Two places are named after Joseph Nisbet LeConte:

• LeConte Point in Hetch Hetchy Valley.
• Le Conte Avenue near the UCLA campus in Los Angeles.
