Remembering Arthur Hardy and the Vietnam War

  By

VietnamMemorialwall

On this Memorial Day, memories of a man I never met suddenly flooded my mind this morning. Arthur H. Hardy died in Laos during the Vietnam War in 1972. I didn’t know him. But yet I remember him.

All of this began with an extraordinary tribute to Captain Hardy by Ipswich Town Historian Gordon Harris. Please take a moment to read it.

I was in my first year of high school when the plane piloted by Hardy was shot down. For many years he would be listed as a POW, then MIA, before his remains were finally found and returned to his family in 1983. In a small town like ours, everyone felt the weight of his premature demise.

Flash forward to 1992, when I moved to the Washington, D.C. area. One of my first forays into town included a sedated viewing of the imposing Vietnam Veterans Memorial in the shadow of the Lincoln Memorial. A long line edged along the narrow path, eyes scanning the wall for the names of loved ones lost. A guidebook helped locate the one veteran from my home town I knew to be listed. Like everyone else, I stared in quiet reverence at the name; it likely seemed an eternity to others, but passed in milliseconds to me.

I still have the rubbing I made that day. Half-sized papers with black borders, along with hard graphite pencils, could be placed over the etched names and the impression kept in remembrance. I have a pair in a single frame that have followed me through several relocations. Another rubbing was taken by my parents, and many years later my mother was able to give it to Arthur Hardy’s mother. Tears flow like rivers even still.

So I thank Gordon Harris for writing his tribute and bringing back such vibrant memories. It is only fitting that the photo accompanying this post is of “The Wall” by Norman Rockwell. Like in the painting, the first thing you notice is the grief of the people looking in…but delving deeper you feel the men and women who gave their last full measure of devotion still reaching into our lives today.

Beijing Aquarium – Home of the Rare Chinese Sturgeon

  By ,

After visiting Tian’anmen Square, the Forbidden City, and Mao’s Mausoleum in Beijing, head on over to the Beijing Aquarium. Located within the Beijing Zoo, the aquarium is the largest inland aquarium in the world. One of its specialties is the Rare Chinese Sturgeon Hall.

Beijing Aquarium

The building itself is shaped like a huge conch shell. It relies on over 18,000 tons of artificial seawater to highlight seven main sections: Rainforests, Coral Reefs, Sharks, Whales, a Touch Pool, a Marine Theater, and the aforementioned Sturgeon Hall. Over 1000 marine and freshwater species are bred on site.

Beijing Aquarium sturgeon

Of the 41 aquariums around the world I’ve visited, this one is unique in that it has a large area devoted to sturgeon. These ancient fish in the family Acipenseridae are an oddity of nature. Their skeletons are almost entirely cartilaginous, like sharks, despite being classified as bony fishes since their ancestors actually had bony skeletons. Sturgeons also are at least partially covered with bony plates called scutes instead of scales. Like catfish, they have four barbels, sensory organs near their wide, toothless mouths, that they drag along the bottom substrate as an aid in navigation and food gathering. They are an odd fish indeed.

Most aquariums toss one or a few sturgeon into the big tanks with sharks and other common fish. In Beijing there are dozens of representatives of the 27 known species of the world. The highlight is the Chinese sturgeon (Acipenser sinensis), a critically endangered species considered, like the giant panda, a national treasure in China. Sadly, like many species of sturgeon, the Chinese sturgeon is nearly extinct in the wild due to overfishing and habitat loss.

The aquarium doesn’t stop there. There are also large tanks with beautiful white beluga whales…

…many species of moray eels…

…and quite a few sea turtles.

Given my previous work with jellyfish I’m always drawn to that section of aquariums and the Beijing Aquarium has one of the best displays I’ve seen. Quite a few tanks exhibit different species, with a variety of light effects to highlight their beauty.

Overall I was greatly surprised – and impressed – by the size and quality of the aquarium. During my visit it seemed clear that the zoo and aquarium cater more to local Chinese rather than tourists, most of whom never get beyond the major tourist attractions mentioned in the first sentence above. This focus is emphasized by the signage, most of which is only in Chinese.

So if you’re in Beijing, take a side trip to the Beijing Aquarium. It’s about 3 miles or so northwest of Tian’anmen Square in the Beijing Zoo, reachable by taxi, bus, or even easier, via subway line 4. You won’t be disappointed. More information here.

The Thundering Wet Dry Tortugas

  By

Our small De Havilland Otter hovered a few hundred feet over the seas as the thundering clouds released torrents of rain highlighted by jagged bolts of lightning. The Dry Tortugas were anything but dry.

Most people think of Key West as the end of the Florida keys, but there are several smaller keys stretching beyond the famed home of Hemingway. About 70 miles west of Key West is Dry Tortugas National Park, accessible only by boat or float plane. I flew, though we almost didn’t take off. Cooling our heels at the small Key West airport, we watched the early morning lightning bring in wind-swept squalls. After an hour or so delay we got the okay and eagerly rushed the tarmac to board our 10-person flight. Storm clouds and rain parted in Moses-like fashion, just enough for our plane to squeeze through. Passing over reefs and wrecks we a lit on the water and coasted to the pier moments before the rain doused us once again.

Approaching Dry Tortugas - Ru Sun

For the record, the “dry” part of the name refers the lack of fresh spring water, a major problem for the inhabitants. Tortugas is Spanish for turtles, the name thanks to Ponce de León after seeing several sea turtles around the island.

Dry Tortugas

The main feature of the Dry Tortugas is Fort Jefferson. The largest all-masonry fort in the United States, it was constructed from 1846 to 1875 but nevertheless was never quite finished. During the Civil War concerns grew that the weight of the brick and cannons was causing the small island it sat on to sink. It served as a Civil War prison, though it’s most famous use was to house the four conspirators sentenced for their role in the assassination of Abraham Lincoln. Dr. Samuel Mudd, Edmund Spangler, Samuel Arnold, and Michael O’Laughlen served time in the fort; Mudd’s medical service during a yellow fever epidemic that killed many prisoners (including O’Laughlen) would result in his pardon and release by President Andrew Johnson. This fact is one of the main reasons I went out to the Tortugas.

Another reason is the rich ocean life adjacent to the fort and the other small islands that encompass the 100 square mile National Park. Due to the weather we had only a short time for snorkeling, but still saw many fish and pelicans.

Pelican Dry Tortugas

Rain again cleansed the plane as we skimmed the sea surface, briefly glimpsing a couple of the famed tortugas on the flight back. The skies seemed to light up as we touched down at the Key West airport. At least we could look forward to a delightful afternoon exploring Duval Street and Mallory Square. The Dry Tortugas could have been drier, and we could have seen more turtles, but the experience was still heavenly. This trip included time in the Everglades, in the Keys, and on the reefs, so there is much more still to show and tell. Stay tuned.

Walking Up Waterfalls in Jamaica

  By

You read that right – walking UP waterfalls. Dunn’s River Falls in Jamaica, to be exact, and the experience is magical.

Jamaica is the land of Bob Marley, reggae, and all-inclusive resorts hugging the coast. The adventure began in one of those resorts, at the Grand Bahia Principe Hotel not far east of Montego Bay and nestled into Runaway Bay on the northern beaches.

Jamaica

Squeezed in between rum punches and peaceful beach enclaves were ample reminders of the science all around us. The most noticeable geology near the resort were karst formations in the limestone. Plant life ranges broadly from various palms, bamboo, ferns, mahogany and rosewood in wet areas to cactus in dry areas.

Jamaica

But one of the biggest attractions was a little further east along the coast near Ocho Rios.  Dunn’s River Falls is a terraced waterfall system over 600 feet long. As the river flows downward it cascades over dozens of mini-precipices, dropping from one ledge to another down the hillside, occasionally resting in small pools interspersed in the vertical walls. That vertical is a mere 180 feet or so but the varied dips and dives is what makes the waterfall so special. As does the fact that you can climb it.

Dunn's River Falls, Jamaica

The falls are a major tourist attraction in Jamaica, drawing thousands of visitors a year. We started on the white sandy beach at its base, then joined a line of other intrepid souls carefully hiking up the slippery rocks while lush tropical vegetation cooled us from the morning sun. The water shoes we purchased the night before came in handy as we battled the splashing streams pushing us downward while we forged our way upward. Steadying ourselves in the hands of total strangers a minute before, now suddenly friends (or perhaps, co-conspirators in our survival quest), we reached the top in fulfillment of our goals after about an hour and half trek. Being drenched from head to toe was overwhelmed by the smiles on our faces that warmed us from skin to soul.

Jamaica

Relaxing back at the resort, we reveled in the joy of listening to live reggae music on the veranda while sipping another rum punch and marveling at the science that is all around us.

Thomas Edison – Birth of an Inventor

  By

Edison cover on BNThomas Edison is well known as one of America’s greatest inventors. But how did he get his start? My new book, https://www.barnesandnoble.com/w/edison-david-j-kent/1121320316?ean=9781435162136 (July 2016 release date), takes a look at how Edison fell into a career of invention, feuded with other inventors like Nikola Tesla and George Westinghouse, and changed the world. From the prologue:

One misty morning in 1862, as the Civil War raged throughout the nation, the teenage Tom Edison saved a life, and in doing so set the stage for a career of invention that would change the lives of millions. Lingering at the train station in Mount Clemens, Michigan, Edison was gazing over the freight cars being moved around the rail yard. Suddenly, he noticed Jimmie MacKenzie, the stationmaster’s young son, playing on the tracks and oblivious to a rail car speedily approaching. Recognizing the danger, Edison “made a dash for the child, whom he picked up and lifted to safety without a second to spare, as the wheel of the car struck his heel.” Falling hard along the gravel embankment, both Edison and Jimmie cut their faces and hands, but were otherwise unharmed. It was the scare of their young lives. In return for his heroic act, the stationmaster offered to teach Edison the art and science of telegraphy, and Edison accepted. This decision would change his life—and ours.

There was another profound impact from his train days – deafness.

He recounted being roughly lifted onto the train by his ears, at which point he heard a “pop!” After that, his hearing steadily degenerated. Another report suggests a baggage master on the train “boxed his ears.” Or perhaps it was a history of illness as a child or a congenital disease? Although the cause is unknown, Thomas Edison became progressively hard of hearing during his lifetime, which impacted both his inventive ability (he claimed the affliction helped him concentrate better) and his attitude (he would “not hear critiques at convenient times”). His hearing impairment played a recurring, and sometimes ironic, role during his long career.

These two fundamental events as a young man helped shape his personality and his career path. Suddenly the idea of toiling away all night and day in the lab doesn’t seem so surprising. That said, there are many things you don’t know about Thomas Edison.

Edison: The Inventor of the Modern World is due out in July 2016 from Fall River Press, Sterling Publishing. The Nook e-book version is already available for pre-order on the Barnes and Noble website. The hardcover book will be available for pre-order shortly. Please help spread the word and watch for more previews here.

Abraham Lincoln Close Up

  By ,

Like all Presidents, Abraham Lincoln seemed to age decades during his four years in office. On my recent trip to Springfield, Illinois I got to see this close up. As you might expect, there are several statues of Lincoln around town, all of which have been photographed millions of times by the steady stream of tourists into this relatively small city.

I did the same, of course. But I also have a penchant for close ups. It was here that the aging process was brought home to me. Let’s start at the Lincoln-Herndon Law Offices, standing on the corner across the street from the Old State Capitol. Here we find a relatively younger Lincoln the lawyer and statesman with his family, his wife Mary straightening his tie as he prepares to give his 1854 anti-slavery speech. This is a close up:

Young Lincoln

A couple of blocks north you’ll find Union Square Park and, yes, more Lincoln statues. I liked the one of him standing strong against an unseen wind as he gives his first inaugural address. In this close up the flag atop the tower of Union Station highlights a now bearded Lincoln.

Older Lincoln

Now imagine how much older he looked after four years of war.

The statue sits across the street from the Abraham Lincoln Presidential Library and Museum. I spent two days inside the library doing research with the Papers of Abraham Lincoln project, skipping across the street only to see a special exhibit “Unfinished Work” temporarily showing in the museum. I’ll be coming back out to Springfield in September for a full-scale tour of Lincoln-related sites including New Salem, the Lincoln house, and tomb. Even though I’ve just returned, I can’t wait to go back.
