Obit watch: July 16, 2020.

Over the past few days, the paper of record has run two obits that fall into the “obscure outside of a specific niche, but interesting” category.

Jay Riffe. He took up spearfishing when he was 10 years old (“to get food for the table”). He became the Pacific Coast spearfishing champion at 22.

When he died on May 11 at 82, at his home in Dana Point, Calif. — a death not widely reported beyond spearfishing circles — Mr. Riffe left behind a trail of accomplishments in his undersea world, including breaking three world records for deepwater sport fishing; founding Riffe International, a premier American spearfishing and freediving equipment maker; and advancing a campaign for sustainable-fishing regulations. His family said the cause was heart failure.

For nearly 50 years, beginning in the late 1960s, Mr. Riffe built and developed spearguns and other devices that revolutionized the sport in the United States. His company used supple woods, like teak, which could be grooved to fit a spear shaft snugly; corrosion-resistant magnets, which kept spear tips from wobbling; and textured nylon grips, which kept guns from slipping from the spearfisher’s hand.

Louis Colavecchio. He used to make jewelry, but turned his skills to a more lucrative occupation: counterfeiting.

…there was nothing more thrilling than creating counterfeit slot machine coins. The coins he made were so detailed that even federal officials and casino workers found it challenging to distinguish his fakes from legitimate ones under a microscope.

All of Mr. Colavecchio’s work was meticulous. He could toil alone under microscopes for days, filled by a desire to trick the federal government and the casinos. He would not brook the possibility of an error; each die had to be perfect.
“Making counterfeit items must have appealed to me in some way that I didn’t understand,” Mr. Colavecchio wrote in his book.

Mr. Colavecchio perfected his illicit craft over about four years, Mr. Longo said, making thousands of chips and slot tokens for 36 casinos. At one point, the Treasury Department even sought his expertise. According to court records, the department paid him $18,000 after he was released from federal prison in 2000 because his manufacturing dies had outlasted those of the U.S. Mint.

His tokens were masterly because he crushed the originals and got the exact breakdown of their composition, Mr. Longo said. Mr. Colavecchio purchased the material, bought a press and, using a laser-cutting die, made molds and copies.
“It’s like having access to the U.S. Mint on the weekend, printing your money and leaving,” Mr. Longo said.

In case you were wondering, his book is You Thought It Was More: Adventures of the World’s Greatest Counterfeiter, Louis the Coin (affiliate link). I may have to order a copy of that for myself.

Great and good FotB Borepatch sent over a nice obit from ArsTechnica for Grant Imahara, which I very much appreciated. There’s also a very good Hacker News thread.
