Series 1, Assistant Secretary of the United States Army for Financial Management, 1963-1973, documents Becker's posting as Assistant Secretary in the Army.

As Assistant Secretary, Becker initiated a number of reform measures concerning the financial management of Army resources, which are reflected in documents concerned with budgets and cost analysis.

This series also includes personal correspondence dealing with courtesies related to military protocol, along with a few letters on more substantive issues. A few nomination and promotion support letters are located in their own file, however, most of these letters are filed in the alphabetical correspondence files. Additionally, the series contains photographs, speeches, and government publications.

Series 2, Mentor Group, 1989-2007 has been divided into two subseries. The first series contains the working documents maintained by Becker. The second subseries contains publications and other materials related to specific events organized by the Mentor Group.

The Mentor Group was established in 1983 by Thomas Kosmo, who as of 2007 remains president, as a non-profit, publicly supported research institute focusing on constitutional, legal-economic comparative studies. Becker became Chairman of the Advisory Board of the Group in 1989 and as of 2007 continues in that capacity. Central to the development of these studies has been the founding of three interrelated forums:

The Forum for US-EC Legal-Economic Affairs (1989- ; at its beginning known as the Forum for Members of the Supreme Court of the United States and the Court of Justice of the European Communities) is a body concerned with practical legal-economic problems posed by the Internal Market of the European Union and has focused on the future of an integrated economy within a fully democratically developed European Union. Membership in the Forum included senior jurists (including justices from the U.S. Supreme Court and the Court of Justice of the European Communities), economists, and government officials, as well as senior representatives of major industrial corporations from both sides of the Atlantic.

The Forum for Russian Legal-Economic Affairs (1993-2000; at its beginning known as the Troika Conference for Russian Legal-Economic Affairs) was a professional collaboration of Russian and non-Russian jurists, ministers, high government officials, scholars, corporate leaders, and diplomats to serve the Russians variously responsible for the establishment of legal and economic orders that reinforce one another within the Russian Federation.

The Central European Forum for Legal-Economic Affairs (2004- ; at its beginning known as the EU New Member States Forum), in partnership with the Forum for US-EU Legal-Economic Affairs, is a working body for judges, national officials, and the private sector in Central Europe. The Forum is designed to aid in coordinating national and private sector endeavors of the new member states with established EU institutions, especially the European Commission and the Europe Court of Justice.

Becker co-founded the Forum for US-EU Legal-Economic Affairs, along with Thomas Kosmo, the originator of the concept. As co-founder, he has been responsible for corporate fundraising and relations with senior American and European corporate executives and has co-shared agenda planning with Kosmo. Kosmo, in turn, has been responsible for recruiting scholars and jurists from both sides of the Atlantic. Becker was an advisor to the Forum for Russian Legal-Economic Affairs until it was terminated in 2000 and as of 2007 is an advisor to the Central European Forum for Legal-Economic Affairs.

This series contains records documenting the Forum for US-EC Legal-Economic Affairs and the Forum for Russian Legal-Economic Affairs.

The materials in this series are arranged as two subseries: Working Documents 1989-2000 and Forum Meetings and Publications 1991-2007.

Series 3, New York City Director of the Budget, 1959-1971, is divided into three subseries. The first subseries includes published and unpublished reports. The second subseries contains subject files and the third subseries consists mainly of correspondence, handwritten notes, memoranda and working documents related to the budget during and after John Lindsay's 1965 New York mayoral campaign. Becker actively worked on this campaign and then served as his Director of the Budget in 1966. These materials document Becker's role in the campaign in which he helped shape Lindsay's budget platform, as well as the transition to the new administration, including the fiscal recovery plan that Lindsay ultimately implemented during New York's fiscal crisis of 1966.

The materials in this series are arranged into three subseries: Reports 1961-1966; Subject Files 1964-1971; and General 1959-1966.

Series 4, General, 1944-2012 reflects Becker's personal activities. Becker used his financial and analytical skills throughout his career. He created a small file of his position papers, included are documents for the Investment Bankers Association of America, John J. Gilhooley during his bid for New York City Comptroller in 1961, and the Critical Issues Council directed by Milton Eisenhower. Some of these position papers can be found elsewhere in the series, for example the paper on the position of comptroller is found in the portfolio assembled by Becker and within the John Gilhooley correspondence. Other writings in this series include the foreign press reviews from Becker's Army service in the mid-1950s, and a manuscript entitled "Selling Municipal Bonds."

Other records document a fundraising campaign for the Carnegie Hall Corporation, of which Becker served as a trustee, and a proposal for an Urban Industrial Bank. Most of the correspondence related to both Carnegie Hall and the Bank proposal can be found in this series. However, a few letters are found in the personal correspondence files of the Army series.

The materials in this series are arranged alphabetically by subject.

The scrapbooks include numerous invitation cards, a few programs and a handful of letters and press releases. The American Soldier album is a collection of lithographs depicting the American soldier and the uniforms from 1776 to 1965.

Newspaper clippings, press releases, and letters dominate the scrapbook from Becker's time as budget director for New York City.
