The valley's own physicist, come home

The boy who measured the electron and came back to the wall

A quarter mile from where you stand, Harvey Fletcher lies in the rock wall of the cemetery where his life began and ended.

The short answer

American Fork, Utah, is where physicist Harvey Fletcher grew up before helping measure the electron's charge in the Millikan oil-drop experiment and later pioneering stereophonic sound at Bell Labs. He was buried in 1981 within the town's historic cemetery rock wall, alongside Reva Beck Bosone, Utah's first congresswoman.

Mount Timpanogos, sometimes informally referred to as Timp, is the second highest mountain in Utah's Wasatch Range. Timpanogos rises to an elevation of 11,752 ft (3,582 m) above sea level in the Uinta-Wasatch-Cache National Forest. With 5,2 — 2004 · Ken Lund from Reno, Nevada, USA · CC BY-SA 2.0
1884 to 1910s

Fletcher built the equipment that weighed the electron

Harvey Fletcher grew up in American Fork, in the shadow of the mountains that still ring this valley. He left for the University of Chicago to study physics. There he found himself working alongside Harvey Fletcher on one of the most famous experiments in modern science. Millikan wanted to measure the exact electric charge carried by a single electron. Fletcher built the equipment. He ran the numbers. He worked out how to keep a tiny charged oil drop suspended between two plates long enough to time its fall.

The experiment became known as the oil-drop experiment. It gave physics its first solid measurement of the electron's charge, a number that underpins how atoms and electricity are understood today. Millikan later won the Nobel Prize for the work. Fletcher was still a graduate student. He agreed to let his name stay off the published paper. This decision shaped how the credit was remembered for decades afterward.

The same young man who measured the smallest known charge in the universe would soon turn his attention to something people could hear.
1920s to 1930s

Fletcher's Bell Labs work gave sound its depth

Fletcher moved into industrial research. He joined Bell Telephone Laboratories. Sound itself became his subject. He led experiments into how the human ear separates and locates sound. This work grew into a demonstration of two-channel recording and playback. Engineers under his direction sent music down two microphones. They placed two speakers apart from each other. Audiences heard something new: sound with direction and depth.

That work laid the groundwork for stereophonic sound, the two-channel system now built into nearly every recording made since. Fletcher spent decades at Bell Labs and later at Columbia University and Brigham Young University, still working on acoustics and hearing into old age. He died in 1981, ninety-seven years old, and was brought back to American Fork. He lies now inside the quarter mile. This wall has held the town's dead since the 1800s. It also holds Reva Beck Bosone, Utah's first congresswoman.

1895 to 1983

Utah's first congresswoman rests beside Fletcher's grave

Reva Beck Bosone was born in 1895, over a hundred miles from American Fork. Her ashes came to rest in the same wall as Harvey Fletcher. She trained as a lawyer. She sat as a judge in Salt Lake City. In 1948 she became the first woman Utah sent to Congress. She served two terms. Then she worked for the Interstate Commerce Commission in Washington. She died in 1983. She was buried in the American Fork Cemetery Rock Wall, a few steps from Fletcher's grave.

The wall holds a congresswoman and a physicist within a stone's throw of each other.
1852 to 1868

Settlers buried their dead with their own hands

Before that wall existed, American Fork buried its dead somewhere else. From about 1852 until 1868, the settlement's first cemetery took its early dead. There was no undertaker. Friends and relatives dug the graves themselves and laid out the bodies by hand. The ground filled up. The town moved its burying to the newer cemetery. For decades nobody marked where the first graves had been. In 1948 the Daughters of Utah Pioneers put up a marker listing the names of those still resting there.

Not every life this valley kept came back safely.
1992

A girl was stabbed to death in the canyon

In 1992, a 13-year-old girl was stabbed to death in American Fork Canyon, above the town. Roberto Arguelles killed her there. He later confessed to several other murders around the valley. The canyon that draws hikers and sightseers up from the valley floor had, for one girl, been the last place she went.

2013 to 2019

A 33-acre parcel passed between three governments

The ground under your feet has its own paperwork. In 2013, American Fork City handed this parcel to Utah County by quitclaim deed. Utah County held it until 2019. Then it passed to Highland City. That same year, American Fork City recorded an easement across it. The county created the parcel in 2015. It was just over 33 acres. It was carved out by compass bearings and curves off a section corner surveyed generations ago. It passed between three different governments in less than a decade, without ever holding a home.

Fletcher and Bosone rest a quarter mile off, inside a wall that has held this valley's dead since before any of these deeds were signed.
