On the 80th anniversary of the First Draft of a Report on the EDVAC (June 30, 1945), a moment of appreciation for the first generation of computers it inspired:

EDSAC (via Computer History Museum - image ca. 1948)

Manchester Mk. 1, evolved from the earlier Baby (via University of Manchester - image ca. late 1940s)

IAS Machine (via Institute for Advanced Study - image ca. 1952)

Bobby Broccoli has great in-depth work on engineering and scientific history. This video in specific is ~ 2hr 30 min, but it exists in 3 parts if you need that divided over time, rather than as say a long-form podcast documentary to listen to while working. Though the editing and graphics on this are fantastic for organizing information. Give it a view! TLDR: Remember every single group project you did in school or even every teamwork thing from ttrpg folks you hadn't worked with before, now multiply that. Every engineering effort is the same as a group project and there is no true solo work.

ON THIS DAY:

150 years ago (23 August 1873), the Albert Bridge, which connects Chelsea to Battersea, was opened for the first time.

Here it is depicted by the Illustrated London News, 30 August 1873.

—

Albert Bridge is a road bridge over the River Thames connecting Chelsea in Central London on the north bank to Battersea on the south.

Designed and built by Rowland Mason Ordish in 1873 as an Ordish–Lefeuvre system modified cable-stayed bridge, it proved to be structurally unsound.

Between 1884 and 1887, Sir Joseph Bazalgette incorporated some of the design elements of a suspension bridge.

In 1973, the Greater London Council added two concrete piers, which transformed the central span into a simple beam bridge.

As a result, the bridge is an unusual hybrid of three different design styles. It is an English Heritage Grade II* listed building.

On This Day in New York City History March 23, 1857: The first commercial passenger elevator is installed by Elisha Graves Otis in the E.V. Haughwout Building. The Haughwout Building was home to a five-story department store at 488 Broadway on the corner of Broadway and Broome Street in what is today the SOHO neighborhood of NYC. The elevator came at a cost of $300 dollars which in today's dollars would cost $10,373.79.

What made Otis' elevator successful and revolutionary was the safety brake that prevented the elevator from falling. The creation of safe elevators led to building being built higher up into the sky. Life as we know it in vertical cities of today wouldn't be what they are without the Otis elevators.

masterpiece asks - the kiss

Thanks so much to@i-c-stars for the ask!

The Kiss: What is one thing in life that you love?

This. This is a slide rule, and they were used before calculators were invented for complex calculations. I purchased one off eBay last year as a joke, and I have fallen in love. Not with the actual process of doing the calculations, as it tedious and impractical, but with the old ways of doing things that are slipping out of memory. Although this thing is somewhat complicated, for so many years this is just how math was done. The slide rule is what got people to the moon, and now it is has been relegated to the dust bin of engineering history. By learning how to use one, I have been able to participate in that history just a tiny bit, and I love it.

Moving the workshop/studio to a new location.  Last bit of paintwork before the move.

Today's Urban Exploration post takes me to the Bronx with a look at this magnificent church: St. Raymond's Catholic Church located at 1759 Castle Hill Avenue at East Tremont Avenue.

The parish was established in 1842 in the then Westchester Village in what was part of Westchester County. The area would become part of the Bronx in 1895. St. Raymond's has the distinction of being the first Catholic Church in the Bronx.

The original church was built in a converted barn and its first priest was Rev. Felix Villanis. With the unflux of Irish, German and Italian immigrants to the area the parish woulr outgrow their first church.

Set behind the original, Archbishop Corrigan laid the cornerstone for the present church on October 10, 1897. The church was designed by George H. Streeton in the Byzantine Revival-style. Amazingly the church was dedicated on October 23, 1898.

The church would grow to include an elementary school (1908), convent (1928), rectory (1931), brothers residence (1942), boys high school,Academy for girls (high school) and an auditorium and gymnasium that is still in operation today. St. Raymond Cemetery is the only Catholic cemetery in the Bronx.
