1911-1915 - Lafayette College

Starting 1911 Robert Swan Mueller I attended Lafayette College. In the Allentown Democrat (Oct 14 1915), in the wedding description for Robert Swan Mueller I, it says that Mueller completed 4 years of college and graduated in 1915. (For this reference, see the clipping here : ).

Robert Swan Mueller I is identified in the 1912 Lafayette College yearbook, and was identified as a prospective 1915 graduate of Lafayette. (A link to the full PDF of the book for "Biographical catalogue of Lafayette college, 1832-1912" is here : [aa1][ GDrive ] ). 1911-1912 was his freshman year.

1915 (April) - Engagement to Anna Elizabeth Freeman

The engagement of Miss Anna Elizabeth Freeman to Robert Swan Mueller was announced in the Pittsburgh Press newspaper on April 8, 1915. Robert Swan Mueller I would have been about 22 years old at the time of his engagement/wedding to Anna. Anna Elizabeth Freeman was born in 1892 [aa10][ GDrive ]. The bride's parents were including DR. Edward Jacob Freeman (born 1851) (of Freemansburgh, Pennsylvania), means both the bride and groom (father was Dr. Gustave Adolph Mueller ) had parents who were doctors. (See full newspaper page at [aa2][ GDrive ] , with clip shown below.

[aa28][ GDrive ]

Is Miss Anna Elizabeth Freeman in the Bethlehem Steel family? We believe so.

John Knecht married Eliza Reigel on Feb 2, 1841 Their 4th daughter was Emily J Knecht,

Emily J Knecht married Dr. Edward Jacob Freeman (b Dec I8, I851) . Dr E J Freeman and Emily J (Knecht) Freeman had 4 children; Only one lived to be an adult - Anna ("Nan") Elizabeth Freeman ,

Who is John Knecht ? "With keen business foresight, Mr. Knecht saw the great benefit the Valley might realize from the building of the railroad, and after its completion he inaugurated the movement that resulted in the formation of the Bethlehem Iron Company."

Hypothesis - The family of Robert Swan Mueller I's bride "Anna Freeman" included the unspoken founders of Bethlehem Steel . That would explain the connections to US Shipping Board. And the move to Baltimore. And the sudden jolt into all the "high society" headlines, and ability to live in nicer homes.

1915-1917 - Pittsburgh PA addresses / Moves to Thomas Blvd in 1916

Robert Swan Mueller I was a "clerk" in the "sales department" at National Metal Molding Company , as of the 1915-1917 Pittsburgh phone books. He is not listed in the 1918 Pittsburgh Directory, suggesting the Mueller family moved to Baltimore before between 1917 and 1918.

The address of Robert Swan Mueller I is listed as "6757 Thomas" in Pittsburgh Pennsylvania, starting with 1916. His father passed a few years prior in 1912, so this home was not inherited from his family. It is a rather large home (still standing today, great neighborhood) for a man is 24 years of age. Presumably, the wealth from his wife's family afforded the young Mueller family to move to this location within a year of his graduation from Lafayette.

Robert Swan Mueller enrolled for the US military Draft Registration. His Registration date was in 1917. His address as of 1917 was 6757 Thomas, in Pittsburgh Pennsylvania (we know he moved there in late 1915 or early 1916). His height is described as "tall".

The 1920 Census: In 1920, the Mueller family has now separated. The new family, with Robert Swan Mueller I now 27 years old and the head of household with wife Anna, has moved their family in 1918 o Baltimore Maryland ("Newland Ave."). They now have two children - Robert Swan Mueller II (who is still referred to as Robert Swan Mueller Jr. in 1920), who is 3 years and 7 months old as of this 1920 census, and John F. Mueller (who we believe is John Freeman Mueller (born 1919) (taking his grandmother's maiden name "Freeman" as his middle name), who is less than 1 year old. ( See full census page form at [aa6][ GDrive ] ).

Robert Swan Mueller I is now identifying his career as "Purchasing Agent" on the 1920 census. History researcher John O'Loughlin comments on Twitter "From the 1920 Census, Robert Swan Mueller I lists his employment, as a Purchasing Agent [...] for the United States Shipping Board !" Information on the USSB can be found here : [🌐United_States_Shipping_Board]. We do not know when Robert Swan Mueller I joined the USSB, but it must have been between mid 1917, but before mid 1920.

Also on the 1920 census, we see that Robert Swan Mueller I's stepmother Nell Mueller (now a widow) and her son (and Robert Swan Mueller's half-brother) Gustav Mueller, have moved to San Diego, California. None of Robert Swan Mueller I's immediate relatives remain in Pittsburgh.

1921 - Move to 12 Englewood Rd. in Baltimore

Based on the Baltimore phone directory, the Mueller family moved to the residence at 12 Englewood Rd in Baltimore between 1920 and 1921. The new Mueller family address is a duplex of a very high-end neighborhood of Baltimore. This is Google Street View today (Jan 2019) of that spot on Englewood Road in Baltimore. Robert Swan Mueller estimated his home value to be about 20,000 USD on the 1930 census (shown later), a time when the average US home price was under 5,000 USD. Combined with several children, and one servant to pay salary for, the 28-year-old Robert Swan Mueller I is apparently doing well financially as of 1921.

1922 (Feb) - Representing "Union Shipbuilding Co." in Baltimore at Local Association of Purchasing Agents

Some info on hulls associated with Union Shipbuilding can be found here : 2016-05-shipbuildinghistory-com-union-shipbuilding-baltimore.pdf /

"Union Shipbuilding Company was established in 1916 by the Riter-Conley Manufacturing Co. of Pittsburgh, a large industrial steel fabricator: the site was in the Fairfield section of Baltimore, on the west side of the harbor, where in 1913 Ellicott Machine Corp. had opened a yard to build dredge hulls. Riter-Conley's President, Thomas Riter, died in 1916, however, and the business was sold to McClintic-Marshall Co., who retained ownership until WWII, when it was acquired by the US government and became part of the Bethlehem Fairfield Shipyard."

1923 (March) - "R. S. Mueller Company" opens in Baltimore

The following information was obtained from the 1935 issues of the periodical "The American Fertilizer". (You can download a copy of all of the volume 59 July-Dec 1923 issues in this PDF at [aa4][ GDrive ] ). A few pages at the front of the July 14, 1923 issue are below:

We see that in March of 1923 (on page 23 of "The American Fertilizer"), Robert Swan Mueller I of Baltimore opened up his company "R. S. Mueller Company" in Baltimore. This solidifies out knowledge that as of March 1923, Robert Swan Mueller I was no longer with the United States Shipping Board, but now owned and operated his own business as a "Chemical broker", with an apparent focus on the fertilizer industry. The person associated with the new business, W. Whiteley Baker Jr. , is an important individual to research. (See his page here : William Whiteley Baker Jr. (b1894) ). The R.S Mueller Company was initially located in the Vickers Building, Baltimore .

The R.S. Mueller Company has several specialties including (but not limited to) Chemical brokering, Chemicals, Fertilizer materials, Fish scrap, and sulfuric acid. The following are all taken from the July 14, 1923 issue.
