April 22 is Earth Day: here's the story of the co-founder who killed, then composted, his girlfriend

Nicknamed the Unicorn Killer because his last name means "one horn" in German, Ira Einhorn (wiki) jumped bail and evaded arrest for 23 years, but eventually the "she went to the neighborhood co-op to buy some tofu and sprouts and never returned" story fell apart.

Ira Einhorn was on stage hosting the first Earth Day event at the Fairmount Park in Philadelphia on April 22, 1970. Seven years later, police raided his closet and found the "composted" body of his ex-girlfriend inside a trunk.

When his girlfriend of five years, Helen "Holly" Maddux, moved to New York and broke up with him, Einhorn threatened that he would throw her left-behind personal belongings onto the street if she didn't come back to pick them up.

And so on Sept. 9, 1977, Maddux went back to the apartment that she and Einhorn had shared in Philadelphia to collect her things, and was never seen again. When Philadelphia police questioned Einhorn about her mysterious disappearance several weeks later, he claimed that she had gone out to the neighborhood co-op to buy some tofu and sprouts and never returned.

At the time of his arrest, Einhorn had a kind of
crazed Colonel Sanders thing going......
It wasn't until 18 months later that investigators searched Einhorn's apartment after one of his neighbors complained that a reddish-brown, foul-smelling liquid was leaking from the ceiling directly below Einhorn's bedroom closet. Inside the closet, police found Maddux's beaten and partially mummified body stuffed into a trunk that had also been packed with Styrofoam, air fresheners and newspapers.

After his arrest, Einhorn jumped bail and spent decades evading authorities by hiding out in Ireland, Sweden, the United Kingdom and France. After 23 years, he was finally extradited to the United States from France and put on trial. Taking the stand in his own defense, Einhorn claimed that his ex-girlfriend had been killed by CIA agents who framed him for the crime because he knew too much about the agency's paranormal military research. He was convicted of murdering Maddux and is currently serving a life sentence.

Understandably, Earth Day's organizers have distanced themselves from his name, citing Gaylord Nelson, an environmental activist and former Wisconsin governor and U.S. senator who died in 2005, as Earth Day's official founder and organizer. According to the U.S. Environmental Protection Agency, Sen. Gaylord Nelson created Earth Day in the spring of 1970 as a way to bring national awareness to the fact that, at the time, there were no legal or regulatory mechanisms in place to protect the environment. About 20 million participants at various Earth Day events across the U.S. made Earth Day a success, and in December of 1970, Congress authorized the creation of a new federal agency to tackle environmental issues — the EPA.

April 18, 1906 - the earthquake and fire that destroyed 80% of San Francisco: documentary and footage

San Fran City Hall
The 1906 San Francisco earthquake (wiki) struck the coast of Northern California at 5:12 a.m. on April 18 with an estimated"moment magnitude" of 7.8 and a maximum "Mercalli intensity" of "XI" ("Extreme"). Severe shaking was felt from Eureka on the North Coast to the Salinas Valley, an agricultural region to the south of the San Francisco Bay Area. 

Devastating fires soon broke out in the city and lasted for several days. As a result, about 3,000 people died and over 80% of the city of San Francisco was destroyed. The events are remembered as one of the worst and deadliest natural disasters in the history of the United States. The death toll remains the greatest loss of life from a natural disaster in California's history and high in the lists of American urban disasters.

Below is a side by side comparison of trolley car trips down Market Street taken 1. on April 14, 1906, four days before quake and fire, and 2. shortly after. Check out the lack of traffic regulation - the trolley car is on a track, but there's no rhyme or reason to anything else - no traffic lights, no lanes, and no rules:

Snake Oil Willie Band:

"Women are teachable": 1940's booklet to “assist male bosses in supervising their new female employees"

The subject has always interested me, because my mom was one of them - the women who went to work during World War II while the men were off fighting, then gave up their jobs and paychecks once those men came back.

You've come a long way, baby. From the National Archives:
By 1944, over half of American adult women were employed outside the home, making invaluable contributions to the war effort. As women went about their duties, supervisors often worried about effectively assimilating them into the workforce. This publication from the Radio Corporation of America (RCA) awkwardly attempted to assist supervisors with managing their new female employees.

When you supervise a woman…
Make clear her part in the process or product on which she works.
Allow for her lack of familiarity with machine processes.
See that her working set-up is comfortable, safe and convenient.
Start her right by kindly and careful supervision.
Avoid horseplay or “kidding”; she may resent it.
Suggest rather than reprimand.
When she does a good job, tell her so.
Listen to and aid her in her work problems. 
When you put a woman to work…
Have a job breakdown for her job.
Consider her education, work experience and temperament in assigning her to that job.
Have the necessary equipment, tools and supplies ready for her.
Try out her capacity for and familiarity with the work.
Assign her to a shift in accordance with health, home obligations and transportation arrangements.
Place her in a group of workers with similar backgrounds and interests.
Inform her fully on health and safety rules, company policies, company objectives.
Be sure she knows the location of rest-rooms, lunch facilities, dispensaries.
Don’t change her shift too often and never without notice.

Whenever you employ a woman...
Limit her hours to 8 a day, and 48 a week, if possible.
Arrange brief rest periods in the middle of each shift. 
Try to make nourishing foods available during lunch periods.
Try to provide a clean place to eat lunch, away from her workplace.
Make cool and pure drinking water accessible.
See that the toilet and restrooms are clean and adequate.
Watch work hazards - moving machinery; dust and fumes; improper lifting; careless housekeeping.
Provide properly adjusted work seats; good ventilation and lighting.
Recommend proper clothing for each job; safe, comfortable shoes; try to provide lockers and a place to change work clothes.
Relieve a monotonous job with rest periods. If possible, use music during fatigue periods.

Finally–call on a trained woman counselor in your personnel department…
To find out what women workers think and want.
To discover personal causes of poor work, absenteeism, turnover.
To assist women workers in solving personal difficulties.
To interpret women’s attitudes and actions.
To assist in adjusting women to their jobs.
The same group of documents in the Archives also has a booklet called ""Womanpower" Campaign". See the whole thing there:
