Mr. Froehlich was born in 1922 and served in the US Navy during WWII as a signalman. He went on to become an aeronautical engineer and worked for Boeing and other companies before ending up at General Mills (the Cheerios people) in his native Minnesota. At General Mills he helped design high-altitude balloons for the US military before being tasked to help build a mechanical arm for the U.S. Navy-owned bathyscaphe Trieste in 1960.

As part of his work on balloons he specialized in designing small spheres able to endure hostile environments. Mr. Froehlich also worked on the design for a self-propelled, two-man deep-sea vessel called the Seapup.
This talent and earlier experience became crucial factors in his selection as the project leader for the design of a new US Navy deep-diving research submersible. That submersible was later named "Alvin" by the US Navy after Allyn Vine of the Woods Hole Oceanographic Institution. Vine another engineer was a key proponent for the U.S. to develop a national program for manned undersea vehicles.
Part of Mr. Froehlich team's unique design was to combine a new buoyant material called syntactic foam with hollow metal spheres to build the vessel. Confident in his design Harold even participated in one the first test dives made in 1964 near Woods Hole, Mass. -- "to the great depth of 27 feet," he later said. Years later Mr. Froehlich told Minnesota Public Radio that winning the bid to design and build Alvin was an astonishing feat, because the Navy initially "was skeptical about a Wheaties company designing a submarine."
With Vine and Navy officer Charles B. Momsen Jr son of "Swede" Momsen., Mr. Froehlich received the 1989 Elmer A. Sperry Award for "the invention, development and deployment of the deep diving submarine, Alvin." The award is sponsored by prominent engineering societies.
After leaving General Mills Mr. Froehlich went on to work for the 3M company, designing surgical equipment and retiring in 1989.
Harold "Bud" Froehich died this past week at the age of 82. An engineer at a food company who designed one of the worlds most famous deep-sea submersibles.

The United States submarine service represented only 1.6% of Navy personnel at the time but suffered the highest percentage of casualties within any of the services; a casualty rate of about 22 percent. They also exacted a terrible price on the enemy accounting for 55% of all the Japanese ships sunk; this included a full third of the Japanese Imperial Navy.
Typically the loss of Submarine included the loss of the entire crew...
I put together this video as a 2007 Memorial Day tribute to those still on "Eternal Patrol".
Lord, this departed shipmate with dolphins on his chest is part of an outfit known as the best.
Make him welcome and take him by the hand. You'll find without a doubt he was the best in all the land.
So, heavenly Father add his name to the roll of our dear departed shipmates still on patrol.
Let him know that we who survive will always keep their memories alive.

Not many of us will ever get that chance but if a cyber-space version will pass then check out the Woods Hole Oceanographic Insititution's Alvin Simulator. Used as a training tool for scientists it has standalone session mode as well as a joined session mode for collaborative missions.
WHOI website provides this description as to the use of the simulator:
"In addition to full mission planning for WHOI scientists, the Alvin simulator was intended to provide applicability as a public relations tool so that users at home would be able to find out about WHOI research.
One of the sumulator's outstanding features is its full functionality as a stand-alone session once the interface is downloaded. All the meters and devices reflect real data that is calculated by the underlying algorithms. Furthermore, scientists as well as public users are allowed to collaborate in teams of up to three persons - just as in the real Alvin cockpit where a team consists of one pilot and two scientists.
Every member's actions in a joined session will influence the virtual dive and will be reflected on all the remote team members displays. In addition, an optional chat tool was provided for communication and surveillance purposes. Since scientists might be separated, the simulator is configured for distributive network-based session management which is supported by a Java 1.3 servlet."
There is a link on the site to an instructional video.You won't be shooting sea monsters, this is primarily a technical training tool full of device controls and system gages used for mission tasks rehearsals.
If the simulator is to techie for you then here is some video footage from Alvin at a depth of 7644 feet.
Scientists do get excited when they see something unusual or unexpected, such as a lake at the bottom of the ocean.

Here's another sample of her music.
Submarines not the place for a low cut evening dress, except if you're the XO on halfway night. But as long as its a museum like the USS Ling I'm all for "Women, Guitars an Submarine Acoustics".

There is now a movement to have one of the new Virginia class attack submarines named after a famous naval vessel of the civil war, Lincoln's secret weapon, the USS Monitor.

The introduction of the innovative USS Monitor could be argued as the end of sailing warships and the beginning of the big iron warships domination of Naval efforts for the next 100 years.
The Cleveland Civil War Roundtable has started a grassroots campaign to have the memory of the USS Monitor honored "For the sake of history, tradition, and symmetry".
Now if only the Navy could put a naval rail gun turret in the sail the "USS Monitor" name would be a sure thing. ;-)
