John J. O'Malley, architect

In my visits to Brooklyn parishes, I have seldom encountered a sign or plaque giving the name of the architect who designed the church.  Fortunately, the Tablet has now run an article about the prolific architect John J. O'Malley, 1915-1970.  Please see the article HERE.  The occasion was his 100th birthday, with Mr. O'Malley's descendants visiting Cathedral College in Douglaston, which he designed.

Much of Mr. O'Malley's work is evident in circular churches and chapels in Queens.  A Wikipedia article lists his extensive accomplishments, including apparently some renovations or extensions. It appears that his brand-new churches (contrasted with renovations) date from 1950 until his death in 1970.  Archbishop Molloy died in 1956, Bishop McEntegart retired in 1968, and Bishop Mugavero replaced him.

Many thanks to The Tablet and the O'Malley family for publicizing his life and work!

According to the Wikipedia article, he designed the following churches in the borough of Brooklyn:
St. Sylvester, Grant Avenue, City Line, obviously built in the O'Malley era.
---
St. Athanasius, Bay Parkway, 1963.  Note the unobstructed view of the altar and the bright, colorful interior and windows.
---
St. Gabriel,  Linwood St. and New Lots Ave., obviously built in the O'Malley era.  The parish cluster is now called Mary, Mother of the Church.  This interior photo shows his style, with unobstructed view.  The parish has a Saturday vigil Mass and three Masses on Sunday.

St. Mary Mother of Jesus, 1968, replacing a church destroyed by fire. A Tablet article dated 6.13.14 describes the fire and the beautiful new church, circular and wheelchair-accessible.
---
St. Finbar, Bath Beach, but the church was built before 1912.  Mr. O'Malley may have designed the former school across the street.
--- Sts. Simon and Jude, listed as Bayside (Queens), but I think Gravesend (Brooklyn). There is a resemblance to the Douglaston seminary frontage.
---
And other parish buildings:
St. Nicholas High School, Catherine St., Williamsburg, now renovated and in use by Queen of the Rosary Catholic Academy.
---
St. Vincent Ferrer elementary school, Flatbush, now used for other purposes.
---
St. Bernard parish school, near Bergen Beach.  This page names John O'Malley's firm as architect of the school, which opened in 1963 and continues in 2015 as a Catholic academy. Across the street is a circular church, but the parish history does not give a date.  It may have been built after Mr. O'Malley's sudden death in 1970.
