Oliver Evans, America's First Great Inventor

People seem to naturally resist adopting a new technology even in the face of evidence that it will improve their lives. We stick with an old and inefficient technology when there is clearly a better way.  Given this natural human tendency, it is all the more remarkable that we have people who love to invent.  In fact, there have always been inventors.  In spite of the certain knowledge that getting people to change is a Herculean task, inventors not only persist, they seem to proliferate.

My list of positive attributes of an inventor would include creativity, persistence, and optimism.  Inventors have an extraordinary faith in their ideas and will endure years of neglect and abuse in an attempt to see that their ideas prosper. As a result of the rocky road that inventors must travel, they also tend to be defensive, prickly, and maybe even a little paranoid.  In short, inventors can be a real pain in the posterior.  When they are not enthusiastically pestering people to invest in their idea, they  are usually complaining about the stupidity of those who won't.

Oliver Evans was one of America's earliest inventors.  He is also is a great example of the inventor archetype. Evans was born a few miles west of Wilmington, Delaware in 1755. He was apprenticed as a wheelwright and wagon maker but he quickly gravitated towards ideas related to flour milling. In 1790, the first year of the newly-opened U.S. Patent Office, Evans received the third patent ever issued for his fully-automated flour mill.  His invention was a significant advance in the way flour mills had been constructed.  His new design not only saved a tremendous amount of the hard labor of lifting and carrying the intermediates of the flour milling process from place to place inside the mill, Evans' invention also improved the overall cleanliness of the finished flour.  Previously, millers in their work would walk across the ground flour that had been spread out on the floor to cool and dry, transferring dirt from their shoes into the flour.  Sometimes, the entire batch had to thrown out because it was too dirty.  Evans' automated mill spread the flour out evenly without the need for any manual operations and hence it remained clean.

Despite all these advantages, millers at first saw no reason they should invest in his new-fangled milling equipment.  The old ways were tried-and-true, reliable, a real craft that demanded the miller's best efforts.  Milling couldn't simply be replaced with automated equipment - or so said the millers vested in the old ways of doing things.

Undaunted, Oliver Evans built his own automated flour mill and word started to get around that maybe this peculiar young man (inventors are often seen as a little odd) had something after all.  It wasn't Evans who convinced them to change.  It was a few of what today we would call "early adopters" who were willing to embrace Evans' new milling methods. Their success did more to convince their conservative brethren than all the evangelizing by the inventor.  Every inventor is made or broken by the early adopters.

When more millers did decide to try Evans revolutionary new method, they did what people have always done - they declared that the inventions were so obvious that they felt no moral obligation whatsoever to pay Evans his license fees for his patent.  They simply pirated the inventions.  Not everyone was so dishonest, of course.  George Washington paid Evans for a license to use his inventions in Washington's own mill on the Mt. Vernon estate.  A bit later, Thomas Jefferson did as well.

Evans' patent lapsed in 1804 after its 14-year patent life. Due to all the pirating of his invention, Evans never felt he was fairly compensated for his invention.  In a rare bit of legislative compassion, the U.S. House of Representatives in 1808 gave Evans a 14-year extension of his patent to allow him to again try to collect his patent license fees.  He didn't live to see the end of the patent extension. By the time of his death, he had become completely jaded on the legal protections offered by patents and railed against their usefulness as an incentive for inventors.  Evans wrote his own epitaph which perfectly expresses both the excitement and the frustration of the inventor.

This stone and sod, combined to hold
A wreck'd volcanic engine; old
Which steady wrought on, sixty years
then faulter'd and did need
Here is the end of Oliver, he died
____day of _____
Where has the active spirit flown
Who formed opinions, of its own?
Did disregard the laughs of fools
The Claims of things, the pomp
of schools...
As he wished others do to him
Just so, he strove to do to them
in this straight course, his Bark
did steer
And never felt a pang of fear.

Oliver Evans died on April 15, 1819 but in his many productive years, Evans would leave a legacy of inventions.  He conceived (and patented) America's first powered land vehicle in 1787.  He foresaw the day when railroads would travel at great speed, carrying passengers between cities, even traveling safely at night.  In 1804, he patented the high-pressure steam engine which would open the door to river navigation on the Ohio and Mississippi Rivers.  He built a steam-powered dredge he named the Oruktur Amphibolos (amphibious digger) for the City of Philadelphia. He was the first to invent a practical refrigerator based on cooling from the expansion of ether.  The breadth of his creativity was astounding.

Evans was a self-taught man whose book, The Young Mill-wright and Miller's Guide, on the design and construction of water-powered mills would remain in print through fifteen editions (up to the Civil War). He also published a well-received guide to the design of high-pressure steam engines.

It is intriguing to speculate if there is such a thing as a born inventor.  The more I read, the more I believe that invention is almost like a drug: it seizes receptive people with its creative power and fills their brains with something that is akin to an addicting drive.  Once experienced, the inventor seems to have little choice but to drive forward to either success or exhaustion.

Most of us (myself included) have never experienced the "inventor's high".  Probably the closest we come to it is when we think of a clever way to solve some problem at work or school.  But this is not invention.  These simple problem-solvers don't contain the power to change the world.  True invention can be a dangerous substance.  I would guess that some future inventors would opt out if they knew what the path before them held.  We're all the better that they can't see what's ahead.  They're the better for doing it.

Realtime Innovation

I have been seeing the buzz around Google's new instant search service called Google Realtime.  I hadn't tried it so I wandered over there this morning to see for myself.  The search box looks much the same as the standard Google search window but the results come from blogs, tweets, and other social networking sites and are displayed in near-realtime.

I typed in "innovation" and sat back to watch the action.  I wasn't disappointed.  A new posting containing the word "innovation" would pop up on average every three seconds.

 It was mesmerizing to see this flow of consciousness being spewed forth - all in the name of innovation.  Most of the torrent of returns were tweets - some from companies but many from bloggers who seem to be pushing innovation as a way to get consulting gigs.

The Google site itself is somewhat innovative but you get the same effect of watching the stream if you monitor Twitter or Facebook for a time.  But the effects of aggregation take Google Realtime to another level.

The question that I am struggling with is whether all of this gushing of web consciousness on innovation helps anyone become more innovative?  A debate team taking the Pro position might argue that this shows how much innovation is a part of our collective consciousness, how easily we can cross-pollinate ideas, or how much more easily we can find other people who can help us achieve some specific goal.  The team for the Cons would say this isn't dialogue, it is a monologue with people spewing forth tweets simply in an attempt to be visible, that the people who are really innovating aren't spending their time tweeting, they're actually innovating, or that the chatter actually contributes to less innovation because it is so distracting.

Having read quite a bit about this history of technology and innovation, I come away more on the side of the Cons than on the side of the Pros.  It seems to me that most innovators have a single-mindedness that shuts out all extraneous voices.  I think about John Fitch and the first steamboat, or Oliver Evans automating the first flour mill, or Henry Ford and his plan to put America on wheels with the Model-T, of even more recently, Steve Jobs bringing us a succession of "gotta-have" Apple products.  True innovators are tuning the noise out while they doggedly press forward against all the naysayers.

I remain convinced the we have many innovators today, just as we have had them throughout our history.  They just aren't getting carpal tunnel syndrome from overuse of their thumbs on their Blackberries, tweeting away constantly.  There is a place for all the latest tweets.  I write them myself on my companion Facebook and Twitter pages.  But this is more akin to journalism than it is to innovation.

Now, if you will excuse me, I have some tweets I have to get out.

The Century of Progress: Chicago, 1933

A couple of days ago, I was looking for something on my bookshelves when I got waylaid by a couple of books I had inherited from my Dad when he passed away a couple of years ago.  The first book was entitled, "The Official Pictures of A Century of Progress Exposition, Chicago 1933."  The book was the glossy souvenir book offered at the Exposition for those "take home" memories.  The second, a book of the same title, was a series of watercolor paintings of scenes from the Exposition.

My father visited the Exposition when he was eleven-years old - and he never forgot it.  The Century of Progress was a marvelous display of the latest in technology and architecture.  Just 40 years earlier, Chicago had hosted the World's Columbian Exposition, the so-called White City.  The 1933 Exposition was deliberately designed to be the opposite of the White City.  The architecture of the buildings was entirely modern rather than classical.  The buildings were painted in vibrant colors rather than a monochrome white, engendering the name "The Rainbow City".  The Exposition intended to look forward, not back. The motto of the fair, "Science Finds, Industry Applies, Man Conforms", was intended to be uplifting, even if today it carries more Orwellian connotations.

Despite the efforts to differentiate it, the 1933 Century of Progress had a lot in common with its earlier predecessor. Both expositions were held in the middle of a severe economic depression.  Both attempted to put on a brave face and look past the tough times.  Both were mostly compendiums of artifacts displaying what mankind had created. Both featured a major ride to awe the visitors (the Ferris Wheel in 1893 and the Sky Ride in 1933).  Both were built on the Lake Michigan shoreline and featured a Midway for amusement to complement the educational displays.  Most of all, both were proud proclamations by the City of Chicago showing that it was the leading industrial city in America.

Given that only 40 years had elapsed between the two expositions, many people could certainly have attended both.  But the differences between those two fairs were astounding. In 1893, automobiles were only in their earliest infancy.  By 1933, some of the largest pavilions were built by GM, Ford, and Chrysler.  In 1893, electricity had barely begun to be available in most homes and businesses.  By 1933, it was becoming ubiquitous.  The list goes on to include airplanes, radio, talking motion pictures, and the first experiments in television. There were clearly more technology changes in the 40 years between 1893 and 1933 than there were in the next 40 years from 1933 to 1973.

When I look at the photos of both of these past expositions, I lament how little of them remains.  Like the White City, the Rainbow City of 1933 - 1934 was quickly torn down after The Century of Progress Exposition was finished. Maybe that is as it should be.  Having visited Epcot at Disney World many times over the years, the excitement of the exhibitions begins to fade with repetition. I would guess that much of what was created for the 1933 Exposition was eventually destroyed.  That's a pity given the number of museum-quality displays and diorama that were built for the Exposition.

In 1933, the World's Fair was called The Century of Progress. In 2010, the World's Fair in Shanghai is called Expo 2010 - but it could easily be called The Century of Progress.  So far, every year marks a century of advancement. Given our current world problems, let's hope it stays that way.
